Phase changes

Front

What happens to particles when the temperature of matter decreases?

Back

The particles slow down and move closer together.

Front

What happens to particles when the temperature of matter increases?

Back

The particles speed up and move farther apart.

Front

What is melting?

Back

Melting is the phase change from solid to liquid.

Front

What is sublimation?

Back

Sublimation is the phase change from solid to gas.

Front

What is the freezing point of a substance?

Back

The temperature at which a substance in the liquid state freezes is the same as the temperature at which the substance melts.

Front

What is condensation?

Back

Condensation is the phase change from gas to liquid.

Front

What is evaporation?

Back

Evaporation is the phase change from liquid to gas.

Front

What is the boiling point?

Back

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

Front

What is the relationship between temperature and particle movement?

Back

As temperature increases, particle movement speeds up; as temperature decreases, particle movement slows down.

Front

What is deposition?

Back

Deposition is the phase change from gas to solid.
