What’s the Matter?
What is Matter? All matter is made up of tiny particles also known as atoms. All particles of 1 substance are the same. Different substances are made of different particles.
Particle Theory of Matter The spaces between the particles are large compared to the sizes of the particles themselves. The particles are always moving. The more space the particles have, the faster they move and vice versa. There are attractive forces between the particles.
