Density Review

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

What is the formula for the volume of a rectangular prism?

Back

Volume = Length x Width x Height.

Front

What is the unit of volume in the metric system?

Back

The unit of volume is milliliters (mL) or cubic centimeters (cm³).

Front

If a liquid has a mass of 20g and a volume of 10mL, what is its density?

Back

Density = 20g / 10mL = 2g/mL.

Front

What happens to the density of an object if its mass increases but its volume stays the same?

Back

The density increases.

Front

What happens to the density of an object if its volume increases but its mass stays the same?

Back

The density decreases.

Front

What is the density of water?

Back

The density of water is approximately 1g/mL.

Front

How can you determine if an object will float or sink in water?

Back

If the object's density is less than 1g/mL, it will float; if it is greater, it will sink.

Front

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

Back

Mass is directly proportional to density and volume; as one increases, the others can change depending on the context.
