Density

Front

What is density?

Back

Density is the mass of an object divided by its volume, usually 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

What units are used to measure density?

Back

Common units for density are grams per milliliter (g/mL) and grams per cubic centimeter (g/cm³).

Front

What two properties do you need to find density?

Back

Mass and volume.

Front

If an object has a mass of 10g and a volume of 2mL, what is its density?

Back

Density = 10g / 2mL = 5g/mL.

Front

What does it mean if an object is less dense than water?

Back

It means the object will float in water.

Front

What does it mean if an object is more dense than water?

Back

It means the object will sink in water.

Front

What is the density of water?

Back

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

Front

How does temperature affect density?

Back

Generally, as temperature increases, density decreases because substances expand.

Front

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

Back

Density is a ratio of mass to volume; if mass increases while volume remains constant, density increases.
