What is matter?

Matter is all the “stuff” that exists in the universe. Everything you can see and touch is made of matter, including you! The only things that aren’t matter are forms of energy, such as light and sound. In science, matter is defined as anything that has mass and volume. Mass and volume measure different aspects of matter.

is a measure of the amount of space that a substance or an object takes up.

The basic SI unit for volume is the cubic meter (m³), but smaller volumes may be measured in cm³, and liquids may be measured in liters (L) or milliliters (mL). How the volume of matter is measured depends on its state.

How could you find the volume of air in an otherwise empty room?

• If the room has a regular shape, you could calculate its volume from its dimensions. For example, the volume of a rectangular room can be calculated with the formula:

  Volume = length × width × height

• If the length of the room is 5.0 meters, the width is 3.0 meters, and the height is 2.5 meters, then the volume of the room is:

  Volume = 5.0 m × 3.0 m × 2.5 m = 37.5 m³

Multiple Choice

What is the volume of the dinosaur in the diagram below?

• 1 ml

• 0,8 ml

• 1,5 ml

A: The volume of the water alone is 4.8 mL. The volume of the water and dinosaur together is 5.6 mL. Therefore, the volume of the dinosaur alone is 5.6 mL – 4.8 mL = 0.8 mL.
