Front

What is the formula for density?

Back

density = mass / volume

Front

Buoyancy doesn't only happen in water, it can also happen in the _________.

Back

air

Front

What is a fluid?

Back

Any substance that can flow and take the shape of the container that holds it.

Front

What is the relationship between buoyancy and density?

Back

An object will float if its density is less than the density of the fluid it is in.

Front

What is Archimedes' principle?

Back

A body immersed in a fluid experiences a buoyant force equal to the weight of the fluid it displaces.

Front

What happens to the buoyant force as the volume of displaced fluid increases?

Back

The buoyant force increases.

Front

What is the effect of temperature on the density of a fluid?

Back

As temperature increases, the density of most fluids decreases.

Front

What is the unit of density?

Back

Kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³).
