Chapter 1- Kinetic Particle Theory

Condensation

The process of changing from a solid to a liquid.

Sublimation

The process of changing from a solid to a gas directly.

Evaporation

The process of changing from a liquid to gas below the boiling point.

Vibrate

and rotate about fixed positions.

Matter

Anything that has a mass and occupies space.

molecular mass

It depends on the (rate of diffusion decreases with an increase in mass) and temperature (rate of diffusion increases with an increase in temperature .)

Kinetic Particle Theory

The theory which states that all matter is made up of tiny particles that are in constant and random motion.

Freezing

The process of changing from a liquid to solid.

Melting

The process of changing from a solid to a liquid.

Boiling

The process of changing from a liquid to a gas.

Diffusion

The movement of particles from higher to lower concentrations to fill up any space is diffusion.
