Physical Properties & Solutions Practice

Front

What is the freezing point of a substance?

Back

The temperature at which a substance changes from a liquid to a solid. For example, the freezing point of water is 0°C.

Front

What is a solute in a solution?

Back

The substance that is dissolved in a solvent to form a solution. For example, in a saltwater solution, salt is the solute.

Front

What phase changes occur during freezing?

Back

Freezing is the phase change from liquid to solid.

Front

What phase changes occur during melting?

Back

Melting is the phase change from solid to liquid.

Front

What is the relationship between pressure and phase changes?

Back

Increasing pressure can change the phase of a substance; for example, increasing pressure can cause a gas to condense into a liquid.

Front

What is sublimation?

Back

Sublimation is the phase change from solid directly to gas without passing through the liquid phase.

Front

What is deposition?

Back

Deposition is the phase change from gas directly to solid without passing through the liquid phase.

Front

What is the boiling point of a substance?

Back

The temperature at which a liquid turns into vapor. For example, the boiling point of water is 100°C at standard atmospheric pressure.

Front

What is a solution?

Back

A homogeneous mixture of two or more substances, where one substance (the solute) is dissolved in another (the solvent).

Front

What is the difference between a saturated and unsaturated solution?

Back

A saturated solution contains the maximum amount of solute that can dissolve at a given temperature, while an unsaturated solution can still dissolve more solute.
