Density

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is calculated using the formula: density = mass / volume.

Front

What is the formula for density?

Back

density = mass / volume

Front

What units are used to measure density?

Back

The units for density are typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

What units are used to measure mass?

Back

The units for mass are grams (g) or kilograms (kg).

Front

What units of measurement are used for volume?

Back

The units for volume are milliliters (mL) or cubic centimeters (cm³).

Front

If an object has a mass of 10 g and a volume of 5 cm³, what is its density?

Back

Density = mass / volume = 10 g / 5 cm³ = 2 g/cm³.

Front

How does temperature affect density?

Back

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

Front

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

Back

If the mass increases while the volume remains the same, the density of the object increases.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³ at 4°C.

Front

If an object has a density less than 1 g/cm³, will it float or sink in water?

Back

It will float in water.
