The hydrogen of the water molecule is attracted to chlorine ions and the oxygen to the sodium ions. This allows the sodium and chlorine ions to be pulled apart by the water molecules. Salt dissolves in water because the attraction between the water molecules and the sodium ions or chlorine ions is stronger than the attraction between the sodium ions and chloride ions in the lattice.For every sodium ion you will find one chlorine ion (1:1 ratio). Salt is made up of many sodium and chlorine ions stacked together in a lattice.This kind of unusual negative thermal expansion is related to strong, intermolecular forces, orientation-dependent, or interactions and it is observed in the form of molten silica. It tends to expand and become less dense as it cools more.When liquid water is chilled from room temperature, it tends to grow increasingly dense, similar to other substances, although pure water is thought to reach its maximum density around 4☌.It is temperature dependent, although the relationship is described as non-linear and unimodal rather than monotonic.Water has a density of roughly 1 gramme per cubic centimetre (1 g/cm 3).The following are some of the elements that influence water density. Factors that Influence Water densityĪ substance's density can be influenced by a number of things. Water, for example, has a density of 1 gramme per cubic centimetre, but the density of the Earth is 5.51 grammes per cubic centimetre. The density of a substance is usually measured in grammes per cubic centimetre. The density of Water Formulaĭensity is calculated using the formula d = M/V, where d represents density, M is mass, and V is volume. With salinity, the density of saltwater changes as well. Seawater can reach a density of 1050 kg/m 3 or greater deep in the ocean, under extreme pressure. The density of salt water is 1023.6 kg/m 3 at a temperature of 25 ☌, a salinity of 35 g/kg, and a pressure of 1 atm. Water has a density of 0.99823 g/ml at normal temperature There is no such thing as absolute density when it comes to water. The unit weight of water is one gram per cubic meter at 25 degrees celsius. As a result, at 4 ☌, the density of water reaches its maximum. The water molecules slow down and the density increases when the temperature of warm water drops. The density of the liquid increases as the water molecules become closer together. Why is the density of water highest at 4 degrees Celsius? The water reaches its maximum density at a temperature of roughly 4☌ or 39☏, as we all know. density of water at 4 degrees celsius is 998.97 kg/m 3. The density of water is maximum at 4 degree Celsius i.e. It is the weight of water per unit volume, which is affected by the water's temperature. The density of water is defined as follows: The connection between a substance's mass and the volume it occupies can be described as its density. It's a metric for how densely matter is packed together. The density of water is 1 g per cm3 and density of water in kg per m 3 is 977 kg per m 3.Ī material's density is defined as its mass per unit volume. A substance's density is defined as its mass per unit volume. It is odourless, tasteless, clear, and colourless. Water is the principal ingredient of this planet's lakes, oceans, streams, and the fluids of most living species. The mass of any substance per unit volume of a material is known as absolute density (d). A high density object is one that is hefty and compact. Density can also be defined as the quantity of mass per unit of volume. Density:- Density is a term that describes how much space (volume) an object or substance takes up in relation to the amount of stuff it contains (its mass).

2,526,066, such asbestos fiber was added as a means for retaining an expansive component of the plaster composition in place in the set cast. In one such use the asbestos fiber has been added to plaster primarily to improve the plaster workability or trowelling characteristics while in another instance, in the Croce Patent No. It should be observed also that in some instances asbestos has been used in plaster. "Plaster compositions and products." U.S. A top or white finish coat of smooth plaster.We think this material is meant to refer to what we've labeled the rough-coat or brown coat. The lab report refers to "Grey plaster" wherein it found 1-5% chrysotile asbestos. Rock lath - a plasterboard or gypsum board nailed to the wood framed wall to serve as a plaster base.Notice that according to the lab report, this plaster wall is comprised of the following layers: Thanks to reader TD for providing this photo and asbestos test lab result that confirmed finding asbestos in this plaster sample. See ASBESTOS in DRYWALL Asbestos Confirmed in Rock-Lath Plaster Installation Some plaster products may also contain tremolite (a form of amphibole asbestos) as an inadvertent contaminant from asbestos mining of chrysotile, and also they may include vermiculite that, depending on where it was mined, also contains asbestos (Libby).īecause plaster was added to various wallboard products and drywall to improve its water resistance or fire resistance, in turn that means that additional drywall products manufactured between 19 or later may also contain both chrysotile and tremolite asbestos.Īsbestos was used as an ingredient in some plaster applications.Īsbestos was used in decorative plaster cornices, trim, ceiling medallionsĪsbestos was used also in acoustical plaster both as a direct asbestos additive and as an asbestos contaminant in plasters to which vermiculite or "Zonolite" were added to produce a light-weight plaster having good acoustical properties.Īsbestos was used in plaster designed to have a high resistance to fire.Īsbestos was used in plaster additives to gypsum board or "drywall" products to improve its moisture resistance (such as bath tile backer board) and to meet gypsum board fire resistance standards such as ASTM C630/C630M-03e1 Standard Specification for Water-Resistant Gypsum Backing Board (Withdrawn 2005 and replaced by ASTM C1396/C1396M) However that was not always the case, as we detail here.Īsbestos in Plaster and stucco, sometimes includes chrysotile asbestos in two forms: as a deliberate additive in fire-resistant plaster, in specialty plaster products such as casts or decorative moldings, and on occasion as an inadvertent contaminant. Modern plaster products and modern drywall and taping compound do not contain asbestos. Chrysotile Asbestos content in Some (not all) Plaster We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need.

Let us calculate the ratio of every two successive terms of the Fibonacci sequence and see how they form the golden ratio. In this Fibonacci spiral, every two consecutive terms of the Fibonacci sequence represent the length and width of a rectangle. The larger the numbers in the Fibonacci sequence, the ratio becomes closer to the golden ratio (≈1.618). Each quarter-circle fits perfectly within the next square in the sequence, creating a spiral pattern that expands outward infinitely. The next square is sized according to the sum of the two previous squares, and so on. The spiral starts with a small square, followed by a larger square that is adjacent to the first square. It is created by drawing a series of connected quarter-circles inside a set of squares that are sized according to the Fibonacci sequence. The Fibonacci spiral is a geometrical pattern that is derived from the Fibonacci sequence. It is also used to describe growth patterns in populations, stock market trends, and more. The sequence can be observed in the arrangement of leaves on a stem, the branching of trees, and the spiral patterns of shells and galaxies. The significance of the Fibonacci Sequence lies in its prevalence in nature and its applications in various fields, including mathematics, science, art, and finance. Here, we can observe that F n = F n-1 + F n-2 for every n > 1. The first 20 terms of the Fibonacci sequence are given as follows: Terms of Fibonacci Sequence The terms of this sequence are known as Fibonacci numbers. In simple terms, it is a sequence in which every number in the Fibonacci sequence is the sum of two numbers preceding it in the sequence. The Fibonacci sequence is the sequence formed by the infinite terms 0, 1, 1, 2, 3, 5, 8, 13, 21, 34. Photoshop was initially only available on Macintosh. The list price of Photoshop 1.0 for Macintosh in 1990 was $895. When Photoshop 1.0 was released, digital retouching on dedicated high-end systems (such as the Scitex) cost around $300 an hour for basic photo retouching. The handling of color slowly improved with each release from Adobe and Photoshop quickly became the industry standard in digital color editing. The Barneyscan version included advanced color editing features that were stripped from the first Adobe shipped version. Photoshop 1.0 was released on February 19, 1990, for Macintosh exclusively. While John worked on plug-ins in California, Thomas remained in Ann Arbor writing code. Both showings were successful, and Adobe decided to purchase the license to distribute in September 1988. ĭuring this time, John traveled to Silicon Valley and gave a demonstration of the program to engineers at Apple Computer and Russell Brown, art director at Adobe. Later that year, Thomas renamed his program Photoshop and worked out a short-term deal with scanner manufacturer Barneyscan to distribute copies of the program with a slide scanner a "total of about 200 copies of Photoshop were shipped" this way. Thomas renamed the program ImagePro, but the name was already taken. Thomas took a six-month break from his studies in 1988 to collaborate with his brother on the program. This program (at that time called Display) caught the attention of his brother John, an Industrial Light & Magic employee, who recommended that Thomas turn it into a full-fledged image editing program. student at the University of Michigan, began writing a program on his Macintosh Plus to display grayscale images on a monochrome display. Photoshop was developed in 1987 by two brothers, Thomas and John Knoll, who sold the distribution license to Adobe Systems Incorporated in 1988. Collectively, they are branded as "The Adobe Photoshop Family". As of November 2019, Adobe has also released a full version of Photoshop for the iPad, and while initially limited, Adobe plans to bring more features to Photoshop for iPad. Historically, Photoshop was bundled with additional software such as Adobe ImageReady, Adobe Fireworks, Adobe Bridge, Adobe Device Central and Adobe Camera RAW.Īlongside Photoshop, Adobe also develops and publishes Photoshop Elements, Photoshop Lightroom, Photoshop Express, Photoshop Fix, Adobe Illustrator, and Photoshop Mix. With the introduction of the Creative Cloud branding in June 2013 (and in turn, the change of the " CS" suffix to " CC"), Photoshop's licensing scheme was changed to that of software as a service subscription model. Photoshop CS3 through CS6 were also distributed in two different editions: Standard and Extended. However, in October 2002 (following the introduction of Creative Suite branding), each new version of Photoshop was designated with " CS" plus a number e.g., the eighth major version of Photoshop was Photoshop CS and the ninth was Photoshop CS2. Photoshop's naming scheme was initially based on version numbers. Its feature set can be expanded by plug-ins programs developed and distributed independently of Photoshop that run inside it and offer new or enhanced features. In addition to raster graphics, Photoshop has limited abilities to edit or render text and vector graphics (especially through clipping path for the latter), as well as 3D graphics and video. Photoshop uses its own PSD and PSB file formats to support these features. Photoshop can edit and compose raster images in multiple layers and supports masks, alpha compositing and several color models. "to photoshop an image", " photoshopping", and " photoshop contest") although Adobe discourages such use. The software's name is often colloquially used as a verb (e.g. Since then, the software has become the most used tool for professional digital art, especially in raster graphics editing.

The formula for finding the volume of a rectangular prism is length x width x height.įor example, if you have a rectangular prism that is 8 inches long, 2 inches wide, and 2 inches high, the volume of the prism would be 16 cubic inches. Volume of a rectangular prism is found by multiplying the length, width, and height of the rectangular prism together. They are also popular among hobbyists and artists because they can be easily modified with tools or paint. Rectangular prisms can be used for a variety of purposes, including as part of scientific equipment, in architecture, and as decorative objects. The result is a triangular prism, which can be further broken down into smaller triangular prism shapes. Volume = l * w * h What is a Rectangular Prism?Ī rectangular prism is a three-dimensional solid object that is created when a polyhedron is cut into four equal faces and then sliced along the edges so that each face remains connected to its neighboring faces. The following formulas can be used to calculate the volumes of various shapes: The volume of a rectangular prism is equal to the product of the length, width, and height. This makes it perfect for making light fixtures or sculptures out of metal or plastic. Pyramidal prism is unique because it has a single point at the top and bottom of its shape. Hexagonal prism can be used to build three-dimensional structures because their shapes create six surfaces that can be stacked on top of each other. Trapezoidal prism can be used to measure angles or distances because their shapes make them symmetrical. For example, triangular prisms are great for displaying objects because their shapes create an illusion of depth. Each type has its own unique properties that make it useful for certain applications. There are many different types of rectangular prisms, including triangular, trapezoidal, hexagonal, and pyramidal. This means that a rectangular prism has the same volume as its number of rectangles multiplied together. The sum of the lengths of each rectangle in a prism is equal to the length of the prism itself. They are made up of a series of rectangles that are all the same size and shape. Rectangular prisms are the simplest and most basic geometric shapes. We hope that this information will be helpful in your personal or academic research. Throughout this blog post, we will be discussing the various ways to calculate the volume of a rectangular prism, as well as providing examples. Another way to create a rectangular prism is by taking a triangular prism and cutting it into smaller rectangular pieces. Rectangular prisms can be created in many ways, but the most common is to take a circular prism and cut it into rectangular pieces. Rectangular prisms are a type of polyhedron that have been around since the days of ancient Greece. In this blog post, we will be discussing the volume of rectangular prism definitions and examples.
