Density

Front

What is the formula for calculating density?

Back

Density = Mass / Volume

Front

If an object has a mass of 20 g and a volume of 4 cm³, what is its density?

Back

5 g/cm³

Front

What is the density of water in g/cm³?

Back

1 g/cm³

Front

How do you convert density from g/cm³ to kg/m³?

Back

Multiply by 1000.

Front

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

Back

Density is the ratio of mass to volume.

Front

What is the density of a substance that has a mass of 50 g and occupies a volume of 10 mL?

Back

5 g/mL

Front

Which is denser: a rock with a density of 3 g/cm³ or oil with a density of 0.8 g/cm³?

Back

The rock is denser.

Front

What units can be used to express density?

Back

g/cm³, g/mL, kg/m³

Front

What happens to the density of a substance when it is heated?

Back

Generally, the density decreases as the substance expands.

Front

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

Back

The object with the greater mass has a higher density.
