Density

Front

What is density?

Back

Density is the mass of an object divided by its volume, usually expressed in grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the density of copper if its mass is 216g and volume is 24 cm³?

Back

9 g/cm³.

Front

If an object has a density of 0.6 g/mL, will it sink or float in water (density of 1 g/mL)?

Back

It will float.

Front

What happens to an object with a density less than that of water?

Back

It will float.

Front

What happens to an object with a density greater than that of water?

Back

It will sink.

Front

What is the unit of measurement for mass?

Back

Grams (g).

Front

What is the unit of measurement for volume?

Back

Cubic centimeters (cm³) or milliliters (mL).

Front

What is the density of an eraser with a mass of 4g and a volume of 2cm³?

Back

2 g/cm³.

Front

What is the relationship between density and buoyancy?

Back

An object's buoyancy is determined by its density compared to the fluid it is in; less dense objects float, while denser objects sink.
