1. Coffee is freeze-dried: This is a process known as sublimation, where the solid coffee directly changes into a gas without passing through the liquid state.

2. Ice crystals form on a package of frozen corn: This is freezing, where the liquid water in the corn freezes and forms solid ice crystals.

3. The solid structure of a substance breaks down as liquid forms: This is melting, where a solid substance changes into its liquid state.

4. Water on the street turns to ice during a cold wintry night: This is freezing, where the liquid water on the street freezes and forms solid ice.
