describes the behavior of matter in terms of particles in motion

when no kinetic energy is lost

PV= nRT

a measure of the average kinetic energy of particles in matter

force per unit area

represented by "R"

volume of a gas is proportional to its kelvin temp at constant pressure.

 Fixed amount of volume at a constant tem varies inversely w/ pressure.

Pressure of a fixed amount of gas varies directly w/ kelvin temp 

equal volumes of gases @ same temp & pressure contain equal #s of particles
