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 liquid is more dense: water or syrup?

Back

Syrup is more dense than water.

Front

What happens to objects with a density greater than water when placed in water?

Back

Objects with a density greater than water will sink.

Front

What happens to objects with a density less than water when placed in water?

Back

Objects with a density less than water will float.

Front

Why do different liquids form layers when mixed?

Back

Different liquids form layers because they have different densities.

Front

If a liquid is less dense than another, what can we say about its mass compared to the same volume of the denser liquid?

Back

The less dense liquid has less mass than the denser liquid for the same volume.

Front

What is the density of an object that has a mass of 30 g and a volume of 10 mL?

Back

The density is 3 g/mL (Density = 30 g / 10 mL).

Front

What is the density of a gold piece that displaces 3 mL of water and has a mass of 27 g?

Back

The density is 9 g/mL (Density = 27 g / 3 mL).
