What is the change from a liquid to a solid called?

Back

Freezing

Front

According to Charles' Law, what happens to the volume of a gas when its temperature increases at constant pressure?

Back

The volume increases.

Front

What happens to temperature and pressure in a gas when the gas is heated with a steady plunger?

Back

Temperature goes up, pressure goes up.

Front

Do particles in a liquid move around as freely as particles in a solid?

Back

False, particles in a liquid move more freely than in a solid.

Front

At its boiling temperature, how are the particles of a liquid moving?

Back

Front

What is the process called when a solid turns directly into a gas?

Back

Sublimation

Back

Condensation

Front

What is the term for the temperature at which a liquid becomes a solid?

Back

Freezing point

Front

What happens to the particles in a solid when it is heated?

Back

They gain energy and vibrate more.

Front

What is the relationship between pressure and volume of a gas at constant temperature?

Back

As pressure increases, volume decreases (Boyle's Law).
