Energy due to motion.

• Kinetic energy

• Kinetic-molecular theory

• Elastic collision

• Temperature

Describes the behavior of matter in terms of particles in motion.

• Kinetic-molecular theory

• Kinetic energy

• Temperature

• diffusion

No kinetic energy is lost

• Elastic energy

• Elastic collision

• Kinetic energy

• Diffusion

A measure of the average kinetic energy of the particles in a sample of matter.

• Elastic collision

• Temperature

• Diffusion

• Effusion

The movement of one material through another

• Diffusion

• Effusion

• Grahms law of Effusion

• Pressure

A gas escaping through a tiny opening

• Effusion

• Diffusion

• Pressure

• Barometers

States that the rate of effusion for a gas is inversely proportional to the square root of its major mass.
