Relative Density

Front

What is relative density?

Back

Relative density is a measure of how dense an object is compared to the density of a reference substance, usually water.

Front

What does it mean if an object has a relative density less than 1?

Back

If an object has a relative density less than 1, it means it is less dense than water and will float.

Front

What does it mean if an object has a relative density greater than 1?

Back

If an object has a relative density greater than 1, it means it is more dense than water and will sink.

Front

What is the relative density of water?

Back

The relative density of water is 1.

Front

How does temperature affect the density of water?

Back

As water heats up, it becomes less dense; as it cools down, it becomes denser until it reaches 4°C.

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

Back

A sugar cube is an example of a substance that is more dense than water.

What happens to a piece of wood when placed in water?

Back

A piece of wood floats in water because it is less dense than water.

Front

What happens to sand when placed in water?

Back

Sand sinks in water because it is more dense than water.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.
