Back

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

If an object is less dense than water, what will it do?

Back

It will float.

Front

If an object is more dense than water, what will it do?

Back

It will sink.

Front

What is the relationship between density and buoyancy?

Back

An object will float if it is less dense than the fluid it is in, and sink if it is more dense.

Front

What happens to the relative density of a liquid when you mix it with another liquid?

Back

The relative density may change depending on the densities of the liquids mixed.

Front

How can you determine which of three non-mixing liquids is the most dense?

Back

The most dense liquid will be at the bottom.

What is the term for the ability of an object to float in a fluid?

Back

Buoyancy.

What is an example of an object that is less dense than water?

Back

A piece of wood.

Front

What is an example of an object that is more dense than water?

Back

A rock.

Front

What does it mean if two objects have the same relative density?

Back

They will neither float nor sink in each other; they will remain suspended.
