What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is usually expressed in grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

Front

What is the formula for calculating density?

Back

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, the density of a substance decreases because the substance expands.

What is the density of water?

Back

The density of water is approximately 1 g/cm³ at 4°C.

Front

If a substance has a density less than 1 g/cm³, what will happen when it is placed in water?

Back

It will float.

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

Back

Density is the ratio of mass to volume; increasing mass while keeping volume constant increases density.

What happens to the density of a gas when it is compressed?

Back

The density of a gas increases when it is compressed because the same mass occupies a smaller volume.
