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

What is the formula for calculating density?

Back

Density = Mass / Volume

Front

What units are used to measure mass?

Back

Grams (g) are used to measure mass.

Front

What units are used to measure volume?

Back

Cubic centimeters (cm³) are commonly used to measure volume.

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, density decreases because substances expand.

Front

What happens to the density of an object when its mass increases but its volume remains the same?

Back

The density increases.

What happens to the density of an object when its volume increases but its mass remains the same?

Back

The density decreases.

Front

Why do helium balloons rise in air?

Back

Helium balloons rise because helium is less dense than air.

Front

If an object has a density greater than that of water, will it float or sink?

Back

It will sink.
