8.2 Change of State Flashcard

Front

What is the process called when ice cubes shrink in a freezer?

Back

Sublimation is the process that makes ice cubes shrink as they sit in a freezer.

Front

What happens to the particles in a liquid during the freezing process?

Back

During freezing, the particles in a liquid slow down and take fixed positions.

Front

Is boiling the reverse of freezing?

Back

No, boiling is not the reverse of freezing; melting is the reverse of freezing.

Front

Are evaporation and condensation both types of vaporization?

Back

No, evaporation and condensation are not both types of vaporization; boiling is a type of vaporization.

Front

How do the speeds of water particles in gas compare to those in the liquid state during boiling?

Back

Water particles in gas coming off of a pan of boiling water are moving faster than the particles of the water in the pan.

Front

Define sublimation in the context of phase changes.

Back

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

Front

What is the difference between evaporation and boiling?

Back

Evaporation occurs at the surface of a liquid at any temperature, while boiling occurs throughout the liquid at a specific temperature.

Front

What is condensation?

Back

Condensation is the process where gas changes into a liquid, typically when it cools down.

Front

What is the significance of temperature in the phase change from liquid to gas?

Back

Temperature affects the energy of particles; higher temperatures provide enough energy for particles to overcome intermolecular forces and enter the gas phase.

Front

What is the term for the temperature at which a liquid turns into a gas?

Back

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