Phase Changes (2021)

Front

What is evaporation?

Back

Evaporation is the process by which liquid water turns into water vapor (gas) at temperatures below boiling point.

Front

What is boiling?

Back

Boiling is the rapid vaporization of a liquid, occurring when it reaches its boiling point, transitioning from liquid to gas.

Front

What occurs during melting?

Back

Melting is the phase change from solid to liquid, occurring at a specific temperature known as the melting point.

Front

What is condensation?

Back

Condensation is the process by which water vapor (gas) turns back into liquid water, typically when it cools.

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 deposition?

Back

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

Front

What is the melting point?

Back

The melting point is the temperature at which a solid becomes a liquid.

Front

What is the boiling point?

Back

The boiling point is the temperature at which a liquid becomes a gas.

Front

What is latent heat?

Back

Latent heat is the heat required to change the phase of a substance without changing its temperature.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to temperature.
