Freezing The substances in solid gaining enough energy to break away and form a liquid. Removing heat to return a liquid back to a solid Vaporization The substances in liquid escaping a liquid to form a gas. Condensation Particles in a gas moving closer together to form a liquid. Deposition When a gas turns directly into a solid. Sublimation When a solid turns directly into a gas. Melting Ionization When the atoms of a gas lose electrons, leaving a positively charged nucleus. Melting point When the electrons are recaptured by the positive ions in plasma, causing it to change into a gas. The temperature at which a solid becomes a liquid.
