Relative Density: Evaluate

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 floats?

Back

If an object floats, it means its density is less than the density of the fluid it is in.

Front

What does it mean if an object sinks?

Back

If an object sinks, it means its density is greater than the density of the fluid it is in.

Front

What is density?

Back

Density is the mass of an object divided by its volume.

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 density of water?

Back

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

Front

Give an example of an object that floats in water.

Back

An example of an object that floats in water is a foam block.

Front

Give an example of an object that sinks in water.

Back

An example of an object that sinks in water is a rock.

Front

What happens to oil when placed in water?

Back

Oil floats on water because its density is less than that of water.

Front

What is the relationship between mass and volume in density?

Back

Density is calculated by dividing mass by volume (Density = Mass/Volume).
