Density

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is calculated using the formula: Density = Mass / Volume.

Front

What are the two main measurements that make up density?

Back

Mass and Volume.

How do you determine if an object will float or sink in water?

Back

An object will float if its density is less than the density of water (1 g/mL) and will sink if its density is greater.

Front

What is the formula to calculate density?

Back

Density = Mass / Volume.

Front

If an object has a mass of 20 g and occupies a volume of 5 mL, what is its density?

Back

4 g/mL.

Front

What happens to the density of an object if you increase its mass but keep its volume the same?

Back

The density increases.

What happens to the density of an object if you increase its volume but keep its mass the same?

Back

The density decreases.

Front

What is the density of water?

Back

1 g/mL.

Front

If a block of wood has a density of 0.5 g/mL, will it float or sink in water?

Back

It will float because its density is less than that of water.

What is the density of a substance that has a mass of 30 g and a volume of 10 mL?

Back

3 g/mL.
