Front

What is relative density?

Back

Relative density is a measure of how dense an object is compared to the density of water.

Front

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

Back

It means the object will float in water.

Front

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

Back

It means the object will sink in water.

If Styrofoam floats in water, what can we say about its density?

Back

Styrofoam is less dense than water.

Front

If a rock sinks in water, what can we say about its density?

Back

The rock is more dense than water.

Front

What happens to objects that have the same density as water?

Back

They will neither sink nor float; they will stay suspended in the water.

Front

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

Back

By comparing its density to the density of water.

Front

What is the density of water?

Back

The density of water is approximately 1 gram per cubic centimeter (g/cm³).
