Density

Front

What is density?

Back

Density is the mass of an object divided by its volume. It tells us how much matter is packed into a certain space.

Front

How do you calculate density?

Back

Density = Mass / Volume

What happens to objects with a density less than water?

Back

Objects with a density less than water float.

Front

What happens to objects with a density greater than water?

Back

Objects with a density greater than water sink.

Front

What is the unit of density?

Back

The unit of density is typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

Why do different liquids form layers when mixed?

Back

Different liquids form layers because they have different densities.

Front

If a liquid is less dense than another, where will it be when poured together?

Back

The less dense liquid will float on top of the denser liquid.

Front

What is an example of a less dense object?

Back

A Ping Pong ball is an example of a less dense object that floats on water.

Front

What is an example of a more dense object?

Back

A metal bolt is an example of a more dense object that sinks in water.

Front

How can you tell which liquid is the most dense when they do not mix?

Back

The most dense liquid will be at the bottom when poured together.
