States Of Matter K 2.1 Solids

Solids Matter-anything that takes up space and has mass. States of matter-matter is either in a solid, liquid, gas phase Atom-smallest particle that makes up matter. Kinetic Theory of Matter-Brownian motion

Solids All particles in objects are in constant, random motion. Kinetic – motion Temperature affects the level of molecular motion. No molecular motion at absolute zero. Absolute zero is at 0OKelvin or -273.15OC

Solids At higher temperatures, atoms collide more often. Crystalline solids-repeating geometric patterns. Non-crystalline-amorphous. Non-repeating patterns.

Liquids Liquids have surface tension. Liquids have no definite shape but a definite volume. Surface-tension is caused by cohesive forces between molecules. Viscosity-resistance to flow

Gases Gas – matter that doesn’t have a definite shape or a definite volume. Gas would fill a container completely. Vapor – matter that is in a gas state but generally a liquid or solid at room temperature
