Density

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is calculated using the formula: density = mass / volume.

What tool is used to measure mass?

Back

A balance is used to measure the mass of a substance or object.

What is the formula for density?

Back

density = mass / volume

Front

What is mass?

Back

Mass is a measurement of the amount of matter, or 'stuff', in an object or substance.

Front

What is volume?

Back

Volume is the amount of space that an object or substance occupies.

Why do objects sink or float in water?

Back

Objects sink or float in water because their densities are higher or lower compared to the density of water.

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

How does temperature affect density?

Back

Generally, as temperature increases, density decreases because substances expand and occupy more volume.

What happens to the density of a substance when it is compressed?

Back

When a substance is compressed, its volume decreases, which can increase its density.

Can two objects have the same mass but different densities?

Back

Yes, two objects can have the same mass but different densities if they have different volumes.
