States of Matter and Phase Changes

Front

What is the definition of condensation?

Back

Condensation is the process by which water vapor in the air cools and changes into liquid water.

Front

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

Back

Freezing is the phase change that occurs when a liquid turns into a solid.

Front

What is melting?

Back

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

Front

What is evaporation?

Back

Evaporation is the process by which a liquid changes into a gas, usually due to heat.

Front

What is deposition?

Back

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

Front

What happens during freezing?

Back

During freezing, a liquid loses heat energy and changes into a solid.

Front

What is sublimation?

Back

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

Front

What is the effect of adding heat energy to a solid?

Back

Adding heat energy to a solid can cause it to melt into a liquid.

Front

What is the effect of removing heat energy from a gas?

Back

Removing heat energy from a gas can cause it to condense into a liquid.

Front

What is an example of condensation in everyday life?

Back

An example of condensation is when water droplets form on a cold glass of water.
