Particle Theory of Matter
All matter is made of particles which have spaces between them, attract each other, are constantly moving and move faster as the temperature increases.
a change directly from the solid to the gaseous state without becoming liquid
a form of energy that is transferred by a difference in temperature, and causes changes in states of matter
