Using Particle Theory to explain the properties of solids, liquids and gases. Fill in the blanks
using the key words below. ( Each word can only be used once!)

All substances are made up of _______________________.

The particles in a solid are tightly packed together and can only _______________. They cannot be
pushed any closer together.

The particles in a liquid are in contact with each other, but are arranged ________________. They can
______________ over each other, that is why a liquid can be poured.

The particles in a gas can move around _____________. There are large _____________ between the
particles, so they can be pushed closer. This is why a gas can be compressed.
