Density

Front

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

Density = Mass / Volume

Front

If an object has a mass of 50g and a volume of 10cm³, what is its density?

Back

5 g/cm³

Front

How does temperature affect the density of a substance?

Back

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

Front

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.

Front

What is the density of a material with a mass of 100g and a volume of 50cm³?

Back

2 g/cm³

Front

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.

Front

Calculate the density of an object with a mass of 200g and a volume of 100cm³.

Back

2 g/cm³

Front

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.
