Front

What happens to the volume of a substance as it is cooled?

Back

The volume decreases.

Front

What happens to the density of a substance as it is cooled?

Back

The density increases.

Front

If the volume of substance A is less than the volume of substance B, how do their volumes compare?

Back

The volume of A is less than the volume of B.

Front

What does cold air do in relation to warm air?

Back

Cold air sinks.

Front

When layering liquids of different densities, which liquid will be at the bottom?

Back

The liquid with the highest density will be at the bottom.

Front

Define density.

Back

Density is the mass of a substance divided by its volume (Density = Mass/Volume).

Front

What is the relationship between temperature and density for most substances?

Back

As temperature decreases, density increases.

Front

How does the density of ice compare to liquid water?

Back

Ice is less dense than liquid water, which is why it floats.

Front

What is the unit of measurement for density in the metric system?

Back

The unit of measurement for density is grams per cubic centimeter (g/cm³).

Front

If two substances have the same volume but different masses, how do their densities compare?

Back

The substance with the greater mass has a higher density.
