What is density?

Back

Density is a physical property of matter that describes how much mass is contained in a given volume. It is calculated by dividing mass by volume.

Front

How do you measure volume?

Back

Volume can be measured using measuring spoons, graduated cylinders, or by calculating the dimensions of an object (length x width x height for rectangular objects).

Front

What happens to the mass of an object when it is cut in half?

Back

The mass of the object decreases because you have less material after cutting it.

Front

Which is denser: a fork or an apple?

Back

A fork is more dense than an apple.

Front

What physical property can be observed when an object floats?

Back

The density of the object compared to the density of the fluid it is in.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

If an object has a mass of 10 grams and a volume of 2 cm³, what is its density?

Back

Density = 10 grams / 2 cm³ = 5 grams/cm³.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, usually measured in grams or kilograms.

Front

What is volume?

Back

Volume is the amount of space an object occupies, measured in liters, milliliters, or cubic centimeters.

How does temperature affect the density of liquids?

Back

As temperature increases, most liquids expand, which decreases their density.
