Freezing

Front

Define evaporation.

Back

Evaporation is the process by which molecules in a liquid gain enough energy to enter the gaseous state.

Front

Define melting.

Back

Melting is the process where a solid becomes a liquid when heat is applied.

Front

Define condensation.

Back

Condensation is the process where gas turns into a liquid when it cools down.

Front

Define freezing.

Back

Freezing is the process where a liquid turns into a solid when it loses heat.

Front

What happens to the molecules in a liquid during evaporation?

Back

The molecules gain energy and move faster, allowing some to escape into the air as gas.

Front

What happens to the molecules in a solid during melting?

Back

The molecules gain energy and begin to move more freely, transitioning into a liquid state.
