Density

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is often expressed in grams per cubic centimeter (g/cm³).

Front

What is the formula for 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

Milliliters (mL) or cubic centimeters (cm³) are used to measure volume.

Front

What tool is used to measure mass?

Back

A triple beam balance is used to measure mass.

What happens to an object with a density less than water?

Back

An object with a density less than water will float.

Front

What happens to an object with a density greater than water?

Back

An object with a density greater than water will sink.

Front

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

Back

Density = Mass / Volume = 30g / 10cm³ = 3 g/cm³.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³.

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, the density of a substance decreases because it expands.
