Changes in State

Solid to a Liquid Melting. Melting Point. Where a solid changes to a liquid. Particles must gain energy and become free to move around. Melting Point. The temperature at which melting occurs.

Liquid to a Gas Vaporization: Two types: Boiling Point. Where a liquid changes to a gas. Particles gain more energy and separate from each other. Two types: Boiling Happens at the boiling point Happens throughout the liquid. Evaporation. Below the boiling point. Only occurs at the surface of the liquid. Boiling Point. The temperature at which a liquid boils. Website

Label the type of vaporization.

Melting and Vaporization Video

Gas to a Liquid Condensation Where a gas becomes a liquid. The reverse of vaporization Occurs when a gas loses enough energy to form a liquid. Particles slow down and come back together.

Liquid to a Solid Freezing. Freezing Point. Where a liquid changes to a solid. Particles must lose enough energy that they no longer move around freely. Freezing Point. The temperature at which freezing occurs.

Sublimation Where a Solid changes to a Gas, or and Gas changes to a Solid. The change either way skips the liquid state. Examples: Dry ice. Formation of snow.

Condensation, Freezing, & Sublimation
