Density

Front

What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

What does it mean if an object is less dense than water?

Back

If an object is less dense than water, it will float on the surface of the water.

Front

What does it mean if an object is more dense than water?

Back

If an object is more dense than water, it will sink in the water.

Front

What is relative density?

Back

Relative density is a comparison of the density of an object to the density of water, determining whether it will float or sink.

Front

What happens to a rubber duck in water?

Back

A rubber duck is less dense than water, so it floats.

Front

What is an example of a liquid that is more dense than water?

Back

Honey is an example of a liquid that is more dense than water.

Front

What is an example of a liquid that is less dense than water?

Back

Oil is an example of a liquid that is less dense than water.

Front

How can you determine if an object will float or sink?

Back

You can determine if an object will float or sink by comparing its density to the density of water.

Front

What is the unit of measurement for density?

Back

The unit of measurement for density is grams per cubic centimeter (g/cm³).

Front

If an object has a density of 1 g/cm³, what will happen in water?

Back

If an object has a density of 1 g/cm³, it will neither sink nor float; it will be suspended in water.
