Heat and thermal energy
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 move faster, the temperature goes up. The matter now has both ...
The two rocks have the same mass but different temperatures. Since the 165°F rock is hotter than the 125°F rock, it has more thermal energy.
