Density Triangle Flashcard

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) or grams per milliliter (g/mL).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the unit of density for solids and liquids?

Back

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

Front

What is the unit of density for gases?

Back

The unit of density for gases is typically grams per liter (g/L).

Front

If an object has a mass of 20g and a volume of 5cm³, what is its density?

Back

Density = 20g / 5cm³ = 4 g/cm³.

Front

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

Back

If the mass increases while the volume remains constant, the density of the object increases.

Front

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

Back

If the volume increases while the mass remains constant, the density of the object decreases.

Front

What is the density of water?

Back

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

Front

How does temperature affect the density of most substances?

Back

Generally, as temperature increases, the density of most substances decreases because they expand.

Front

What is the density of aluminum if it has a mass of 40.5g and a volume of 15.0mL?

Back

Density = 40.5g / 15.0mL = 2.7 g/mL.
