What is evidence of a chemical change?

Back

Evidence of a chemical change includes changes in color, temperature, gas production, or the formation of a precipitate.

Front

What happens during evaporation?

Back

Evaporation is the process where liquid turns into vapor, usually occurring at the surface of the liquid.

Front

What is condensation?

Back

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

Front

What is deposition?

Back

Deposition is the phase change where a gas turns directly into a solid without becoming a liquid first.

Front

What is a chemical change?

Back

A chemical change is a change that results in the formation of new chemical substances.

Front

What is an example of a physical change?

Back

An example of a physical change is ice melting into water.
