Density

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in grams per cubic centimeter (g/cm³).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the unit of measurement for density?

Back

The unit for density is grams per cubic centimeter (g/cm³).

Front

If an object has a mass of 30 g and a volume of 10 cm³, what is its density?

Back

3 g/cm³.

Front

What happens to the density of an object if its mass increases while its volume remains the same?

Back

The density increases.

What happens to the density of an object if its volume increases while its mass remains the same?

Back

The density decreases.

Why do objects float in water?

Back

Objects float in water if they are less dense than water.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³.

Front

True or False: The density of a specific material can change based on its temperature and pressure.

Back

True.

Why do helium balloons rise in the air?

Back

Helium balloons rise because helium is less dense than the surrounding air.
