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

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

Back

It will float in water.

Front

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

Back

It will sink in water.

Front

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

Back

Density = 50 g / 10 mL = 5 g/mL.

Front

What is the density of gold if its mass is 27 g and it displaces 3 mL of water?

Back

Density = 27 g / 3 mL = 9 g/mL.

Front

Why do different liquids form layers when mixed?

Back

They have different densities.

Front

Which is denser: oil or water?

Back

Water is denser than oil.

Front

What is an example of an object that floats in water?

Back

A Ping Pong ball floats in water because it has a lower density than water.

Front

What is an example of an object that sinks in water?

Back

A metal bolt sinks in water because it has a higher density than water.
