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 kilograms per cubic meter (kg/m³).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

If an object has a density greater than water (1 g/mL), will it sink or float?

Back

It will sink.

Front

If an object has a density less than water (1 g/mL), will it sink or float?

Back

It will float.

Front

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

Back

The density increases.

Front

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

Back

The density decreases.

What is the density of a crayon with a mass of 10g and a volume of 5 mL?

Back

2 g/mL.

Front

Which object is more dense: one with a mass of 10g and volume of 5mL or one with a mass of 20g and volume of 10mL?

Back
