Density Practice

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

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the formula to find the volume of an object if you know its mass and density?

Back

Volume = Mass / Density.

Front

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

Back

5 g/cm³.

Front

True or False: The density of a material can change with temperature and pressure.

Back

True.

Front

What unit is commonly used to measure mass?

Back

Grams (g).

Front

What unit is commonly used to measure volume?

Back

Cubic centimeters (cm³) or milliliters (mL).

Front

If a substance has a density of 2 g/cm³, what does this mean?

Back

It means that 1 cm³ of this substance has a mass of 2 grams.

Front

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

Back

The density decreases.

What is the density of water?

Back

1 g/cm³.
