Gases

Kinetic Molecular Theory 1)Gases are made of tiny atoms with a lot of space in between them 2)These gas particles are in constant motion, colliding with each other and the walls of their container.

Kinetic Molecular Theory

4 Unique Properties of Gases Property of Gases What that means Ability to FlowCan be poured Low densitySmall mass, big volume CompressibleSqueezable Indeterminate Shape Expand or contract to fill container

Pressure Pressure – comes from randomly moving molecules hitting the surface of a container

Temperature Temperature – comes from motion of molecules - Faster molecules means higher temperature

Boyle’s Law Increase pressure, volume decreases Increase volume, pressure decreases

Charles’s Law Increase temperature, volume increases

Gay-Lussac’s Law Increase temperature, pressure increases Increase pressure, temperature increases
