Mastery Check: 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

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the unit of density?

Back

The unit of density is typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

If two objects have the same mass but different volumes, how does their density compare?

Back

The object with the smaller volume will have a higher density.

Front

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

Back

The density increases.

Front

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

Back

The density decreases.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³.

Front

If an object floats in water, what can be inferred about its density?

Back

The object's density is less than that of water (1 g/cm³).

Front

If an object sinks in water, what can be inferred about its density?

Back

The object's density is greater than that of water (1 g/cm³).

Front

What is the density of a substance with a mass of 100g and a volume of 50cm³?

Back

Density = 100g / 50cm³ = 2 g/cm³.
