density of solids and liquids

This behavior of the density of water explains why ice forms at the top of a body of water. where the Greek letter \(\rho\) (rho) is the symbol for density, m is the mass, and V is the volume. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. The OECD Guidelines for the Testing of Chemicals is a collection of about 150 of the most relevant internationally agreed testing methods used by government, industry and independent laboratories to identify and characterise potential hazards of chemicals. A list of materials needed is included in the resources. The dynamic viscosity of liquids to be investigated should not exceed 5 Pa.s for the hydrostatic balance, and should not be above 500 Pa.s for the pycnometer. 109: Density of Liquids and Solids. %PDF-1.7 %���� 14.2: Fluids, Density, and Pressure (Part 1), [ "article:topic", "authorname:openstax", "fluids", "density", "Pressure", "specific gravity", "license:ccby", "showtoc:no", "program:openstax" ], 14.3: Fluids, Density, and Pressure (Part 2), Table 14.1 - Densities of Some Common Substances, Creative Commons Attribution License (by 4.0), Describe the characteristics of the phases of matter at the molecular or atomic level, Distinguish between compressible and incompressible materials, Compare and contrast the densities of various substances, Explain the relationship between pressure and force. You will need a 100 ml graduated cylinder filled with 50 ml of water and an irregularly shaped object that will fit down into the cylinder. Students will be able to measure the density of solids (regular and irregular shapes) and liquids. Feel free to create or use your own. Includes heavily scaffolded worksheet on density calculations and a cloze exercise. A solid iron bar is an example of a homogeneous substance. Show students a marble, a die and a screw and ask them how they would determine the mass and volume for each. In this chapter, we generally refer to both gases and liquids simply as fluids, making a distinction between them only when they behave differently. With your lab trays all set up and your students all having read the lab and asked their clarifying questions, it is time to start the lab. When a liquid is placed in a container with no lid, it remains in the container. Ask each table group to come up with a working definition that they all agree on for mass, volume and density. The goal here is not a textbook definition but a working definition that makes sense to your students. Table 14.2 shows the density of water in various phases and temperature. Liquids deform easily when stressed and do not spring back to their original shape once a force is removed. By 8th grade, students should have already been introduced to measuring volume, mass and density of solids and liquids. endstream endobj startxref Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. Calculate the mass of the unknown liquid added. If using science journals with indexes, add the words to the index at this time if you like. This lesson should be able to completed in one 50 minute class period. ; We saw that solids and liquids tend to have a high density, whereas gases tend to have a very low density. The SI unit of density is kg/m3. The densities of gases are much less than those of liquids and solids, because the atoms in gases are separated by large amounts of empty space. As an extension to this lesson, I like to assign a few practice problems. Density is an important characteristic of substances. This group of tests covers physical-chemical properties. Commonly refereed to as Archimedes' Principle, where the volume of the submerged portion equals the volume of fluid it displaces. These are only two of many examples of pressure in fluids. endstream endobj 6767 0 obj <>/Metadata 101 0 R/Pages 6764 0 R/StructTreeRoot 114 0 R/Type/Catalog/ViewerPreferences 6781 0 R>> endobj 6768 0 obj <>/MediaBox[0 0 612 792]/Parent 6764 0 R/Resources<>/Font<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI]>>/Rotate 0/StructParents 0/Tabs/S/Type/Page>> endobj 6769 0 obj <>stream Density is determined by dividing the mass of a substance by its volume: \[Density = \frac{Mass}{Volume}\] The units of density are commonly expressed as g/cm 3 for solids, g/mL for liquids, and g/L for gases.
