Density

Front

What is density?

Back

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

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

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

Back

It will float.

Front

What is the principle of displacement?

Back

Displacement is the method of measuring the volume of an object by observing how much water it displaces when submerged.

Front

What is the density of water?

Back

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

Front

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

Back

Density = 10g / 5cm³ = 2 g/cm³.

Front

What happens to the density of an object if you increase its volume while keeping its mass constant?

Back

The density decreases.

Front

What is the formula for calculating the volume of a cube?

Back

Volume = side³.

Front

If a rock has a mass of 20g and a volume of 4cm³, what is its density?

Back

Density = 20g / 4cm³ = 5 g/cm³.

Front

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

Back

Density is a ratio of mass to volume; as mass increases with constant volume, density increases.
