Density Review

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in grams per cubic centimeter (g/cc) or kilograms per cubic meter (kg/m³).

How does the density of ice compare to the density of water?

Back

The density of ice is less than the density of water, which causes ice to float.

Front

What is the formula to calculate density?

Back

Density = Mass / Volume.

Front

If an object has a mass of 50 grams and a volume of 25 cubic centimeters, what is its density?

Back

Density = 50 g / 25 cc = 2 g/cc.

Front

What instrument is used to measure the volume of a liquid?

Back

A graduated cylinder is used to measure the volume of a liquid.

Front

What instrument is used to measure the mass of an object?

Back

A triple beam balance is used to measure the mass of an object.

Front

What is the density of water?

Back

The density of water is approximately 1.0 g/cc.

Front

What happens to the density of an object if its mass increases while its volume remains constant?

Back

If the mass increases while the volume remains constant, the density of the object increases.

Front

What happens to the density of an object if its volume increases while its mass remains constant?

Back

If the volume increases while the mass remains constant, the density of the object decreases.

Front

What is the density of granite if it has a mass of 270 kg and a volume of 100 cc?

Back

Density = 270 kg / 100 cc = 2.7 kg/cc.
