Mass, Volume, and Density

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in grams or kilograms.

Front

What is volume?

Back

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

Front

What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What happens to the volume of an object when it is compressed?

Back

The volume decreases when an object is compressed.

Front

What is the relationship between mass and volume in terms of density?

Back

If mass increases while volume remains constant, density increases; if volume increases while mass remains constant, density decreases.

Front

What is the unit of measurement for volume in the metric system?

Back

The unit of measurement for volume in the metric system is liters (L) or cubic centimeters (cm³).

Front

How does temperature affect the density of liquids?

Back

As temperature increases, the density of most liquids decreases because they expand.

Front

What is the principle of water displacement?

Back

The principle of water displacement states that the volume of water displaced by an object is equal to the volume of the object submerged.

Front

If an object has a mass of 50 grams and a volume of 10 cm³, what is its density?

Back

Density = 50 g / 10 cm³ = 5 g/cm³.
