Condensation
The process of a gas or vapor changing into a liquid.
Deposition
The direct transition of a substance from a gas to a solid without passing through the liquid phase.
Freezing
The process of a liquid changing into a solid due to losing heat.
Fusion
The process of turning a solid into a liquid by adding heat.
Gaseous Phase
The state of matter where a substance has no definite shape or volume and fills its container.
Heat
Energy transfer between systems due to temperature differences.
Heat of Fusion
The heat needed to change a unit mass of a substance from solid to liquid at its melting point.
Solid Phase
The state of matter with a definite shape and volume, particles arranged in a regular pattern.
Sublimation
The process of a substance transitioning directly from solid to gas without becoming a liquid.
Heat of Vaporization
The heat required to change a unit mass of a substance from liquid to gas at its boiling point.
Temperature
A measure of the average kinetic energy of particles in a substance.
Kinetic Molecular Theory
Explains gas behavior by considering the motion of particles.
Vaporization
The process of a liquid changing into a gas by adding heat.
Liquid Phase
The state of matter where a substance has a definite volume but no definite shape, taking the shape of its container.
