Density

Front

What is density?

Back

Density is the mass of an object divided by its volume. It tells us how much matter is packed into a certain space.

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What unit is density commonly measured in?

Back

Density is commonly measured in grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³).

Front

Which is denser: oil or water?

Back

Water is denser than oil.

Front

What happens to objects with a density less than water?

Back

Objects with a density less than water will float.

Front

What happens to objects with a density greater than water?

Back

Objects with a density greater than water will sink.

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 a liquid that has a mass of 200 g and occupies a volume of 100 mL?

Back

Density = 200 g / 100 mL = 2 g/mL.

Front

Which liquid is the most dense: syrup, water, or oil?

Back

Syrup is the most dense.

Front

What is an example of a low-density object?

Back

A Ping Pong ball is an example of a low-density object because it floats on water.
