How Does Heat Flow?

  • Heat flows from warmer objects to colder ones.
  • Do you ever notice the difference in temperature when you touch things?
  • Put your hand on the desk. It feels cold. Your hand is warmer than the desk. Heat is leaving your hand and moving into the desk. That makes your hand feel cold. After a while, the temperature of the desk will be the same as your hand and it won’t feel as cold.
