Chapter 4 Gases

ideal

A gas that obeys these five postulates is a(n) gas.

Kinetic Molecular Theory

The attempts to represent the properties of gases by modeling the gas particles themselves at the microscopic level.

Charless law

describes the volume and temperature relationship of a gas when the pressure and amount are constant.

Boyles law

describes the relationship between the volume and the pressure of a gas when the temperature and amount are constant.

Gay Lussacs law

describes the relationship between the pressure of a gas and its Kelvin temperature if the volume and amount are held constant.

Grahams law

defines the relationship of the speed of gas diffusion (mixing of gases due to their kinetic energy) or effusion (movement of a gas through a tiny opening) and the gases molecular mass.

small particles

Gases are composed of very , either molecules or atoms.
