Density

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 is density calculated?

Back

Density = Mass / Volume.

Front

What happens to the density of a substance when it is heated?

Back

Generally, the density of a substance decreases when it is heated because its volume increases.

Front

What is the unit of density?

Back

The unit of density is typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

True or False: The density of a specific type of material never changes.

Back

True.

Front

What is the volume of 150 grams of lead if it has a density of 11.3 g/cm³?

Back

13.3 cm³.

Front

What density will an object need to float on water?

Back

An object must have a density less than 1 g/cm³ to float on water.

Front

If an object has a density of 0.7 g/cm³, will it float or sink in water?

Back

It will float.

Front

What is the relationship between mass and volume in a graph of a pure substance?

Back

The slope of the line represents the density of the substance.

Front

What is the volume of Object X if its mass is 50 grams and its density is 2 g/cm³?

Back

25.0 mL.
