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 calculating density?

Back

density = mass / volume

Front

If an object has a mass of 200 grams and a volume of 50 cm³, what is its density?

Back

Density = 200 g / 50 cm³ = 4 g/cm³

Front

What is the unit of density in the metric system?

Back

The unit of density is typically grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

Front

How do you calculate the volume of an object if you know its mass and density?

Back

Volume = mass / density.

Front

What is the density of water?

Back

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

Front

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

Back

The density of the object increases.

Front

What is population density?

Back

Population density is a measurement of the number of people living in a specific area, usually expressed as people per square kilometer or square mile.

Front

If a substance has a density of 2.5 g/cm³, will it float or sink in water?

Back

It will sink, because its density is greater than that of water (1 g/cm³).

Front

What is the relationship between density and buoyancy?

Back

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