Phases of Matter Practice

Front

Transition from a liquid to a gas

Back

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

Front

What is the boiling point of a substance?

Back

The boiling point is the temperature at which a liquid turns into a gas, typically indicated on a heating curve.

Front

What happens to particles during vaporization?

Back

During vaporization, particles gain energy and move apart, transitioning from a liquid to a gas.

Front

What does temperature measure?

Back

Temperature measures the average kinetic energy of the particles in a substance.

Front

What state of matter has no definite shape but a definite volume?

Back

Liquid has no definite shape but maintains a definite volume.

Front

What is condensation?

Back

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

Front

What is freezing?

Back

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

Front

What is melting?

Back

Melting is the process where a solid turns into a liquid when it gains heat.

Front

What is sublimation?

Back

Sublimation is the transition of a substance directly from solid to gas without passing through the liquid phase.

Front

What is the difference between a gas and a liquid?

Back

A gas has neither a definite shape nor a definite volume, while a liquid has a definite volume but takes the shape of its container.
