PPT-Chapter 11: Liquids & Solids

The molecular compounds like water ammonia and carbon dioxide have different physical properties because of the intermolecular forces Comparison of all three phases Liquids amp Solids Liquids amp Solids. Flammable liquids. Class I - liquids have flashpoints below 100 degrees F, with vapor pressures not exceeding 40 psia. Class IA - liquids having flashpoints below 73 degrees F and boiling points below 100 degrees F. Beaker.

Overview. Methylene iodide (MI; . ρ. = 3.32 g/cm. 3. ) is used to concentrate material according to density. . When added to MI, materials with greater density will sink while others will float.

In all three states of matter, the atoms or molecules are constantly moving.. Lecture 13 . Silicate Magmas. Basic structural unit of silicates (solid & liquid) is the silica tetrahedron. These are variously joined by shared, or bridging, oxygens, to form various structures in solids and liquids.. Chemistry 4(C). Lesson . Objectives. Compare solids, liquids, and gases. Structure. Compressibility. Shape. Volume . Solids, Liquids, & Gases. Solid. – state of matter that maintains shape and volume. Which one represents a liquid? Why?. Liquids have a definite . volume. , but not a definite . shape. . The particles are closer together than gases so the intermolecular forces are now a factor.. Liquids have a definite .

In all three states of matter, the atoms or molecules are constantly moving.. Beaker. USE:. Holds solids or liquids. Poor accuracy- only estimates volume. Hot Hands. USE:. Use to hold beakers when warm. Should not be used when liquid is boiling. Graduated Cylinder. USE:. Measure volumes of liquids. Erlenmeyer Flask. Erlenmeyer flasks hold solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated.. Florence Flask. Rarely used in first year chemistry, it is used for the mixing of chemicals. Narrow neck prevents splash exposure.. 1. PPT-014-03. Bureau of Workers’ Compensation .
