Back

Because helium is less dense than air.

Front

What is density?

Back

Density is the mass of an object divided by its volume.

Front

What is the unit of density in the metric system?

Back

g/cm³ or kg/m³

Front

How does temperature affect the density of gases?

Back

As temperature increases, the density of gases generally decreases.

Front

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

Back

The density increases.

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.
