How does temperature affect the density of air?

Back

Cold air is more dense than hot air because the molecules in cold air are closer together.

Front

True or False: The density of a specific type of material never changes.

Back

True. The density of a specific material is a characteristic property and does not change under normal conditions.

Front

What happens to the density of most substances when they are heated?

Back

Most substances decrease in density when heated because they expand, increasing their volume.

Front

What is the relationship between mass, volume, and density?

Back

Density is directly proportional to mass and inversely proportional to volume. As mass increases, density increases if volume remains constant.

If a rock has a mass of 28g and a volume of 4cm³, what is its density?

Front

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

Back

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

Front

What is buoyancy and how is it related to density?

Back

Buoyancy is the ability of an object to float in a fluid. An object will float if its density is less than the density of the fluid.
