How is temperature related to thermal energy?
All solids, liquids, and gases are made of matter. Matter is made up of tiny particles that are always moving. The energy from the motion of these particles is called thermal energy. Temperature measures how hot or cold matter is. If the particles in matter slow down, the temperature goes down. The matter now has both ...
