Mass, Volume, and 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 is mass?

Back

Mass is the amount of matter in an object, usually measured in grams (g) or kilograms (kg).

Front

What is volume?

Back

Volume is the amount of space an object occupies, typically measured in cubic centimeters (cm³) or liters (L).

Front

How does density affect whether an object floats or sinks in water?

Back

An object will float if its density is less than that of water (1 g/cm³) and sink if its density is greater.

Front

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

Back

Density = 10 g / 5 cm³ = 2 g/cm³.

Front

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

Back

The density of the object increases.

Front

What is the approximate density of water?

Back

The approximate density of water is 1 g/cm³.

Front

If Block A has a density of 1.2 g/cm³ and Block B has a density of 0.9 g/cm³, which block will float in water?

Back

Block B will float in water because its density is less than that of water.

Front

What is the relationship between mass, volume, and density?

Back

Mass is directly proportional to density and volume; as mass increases, density increases if volume remains constant.
