States of Matter and Phase Changes

Front

What is deposition?

Back

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

Front

Which phase change is NOT a result of adding heat energy?

Back

Deposition is the phase change that does not require adding heat energy.

Front

What phase change occurs when heat energy is removed?

Back

Freezing is the phase change that occurs when heat energy is removed from a liquid.

Front

What is sublimation?

Back

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

Front

What phase change occurs when a liquid turns into a gas?

Back

Evaporation is the phase change that occurs when a liquid turns into a gas.

Front

What is melting?

Back

Melting is the phase change where a solid turns into a liquid due to the addition of heat energy.

Front

What is condensation?

Back

Condensation is the phase change where a gas turns into a liquid when heat energy is removed.

Front

What is freezing?

Back

Freezing is the phase change where a liquid turns into a solid when heat energy is removed.

Front

What is evaporation?

Back

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

Front

What is sublimation?

Back

Sublimation is the process where a solid changes directly into a gas without passing through the liquid phase.
