Solubility

The physical property that describes the ability of a substance to dissolve in a liquid.

Dissolve

To mix completely into a liquid so that the particles spread evenly throughout and form a solution.

Melting

The change of state from a solid to a liquid caused by an increase in thermal energy.

Freezing

The change of state from a liquid to a solid caused by a decrease in thermal energy.

Evaporation

The change of state from a liquid to a gas caused by an increase in thermal energy.

Condensation

The change of state from a gas to a liquid caused by a decrease in thermal energy.

States of matter
