  1. Energy cannot be created or destroyed, it just changes form or moves between objects. There are many different types of energy. Today we will be focusing on thermal energy thermal energy.

  2. Thermal energy is a result of moving particles inside of a substance. Thermal energy can be transferred between objects.

  3. The transfer of thermal energy between two systems of different temperatures is called heat heat. There are 3 different ways to transfer thermal energy: 1. Conduction 2. Convection 3. Radiation

  4. Conduction is the transfer of thermal energy through a solid material transfer of thermal energy through a solid material. Heat is being conducted through the stove burner to the frying pan. Heat is being conducted through the metal pipe to the hand.

  5. Convection is the transfer of heat through liquids and gases by currents Warm air rises, cool air falls. When warm air cools, it falls, creating this cycle. transfer of heat through liquids and gases by currents. Traveling through liquid Traveling through the air (which is made up of gases)

  6. Hot air rises, pushing the hot air balloon upward.

  7. Radiation is heat transfer by waves heat transfer by waves.

  8. When objects of different temperatures come into contact with one another, the thermal energy always travels from the warmer to the cooler warmer object cooler object. Thermal Energy Hot Cold

  9. Heat is always transferred, not coldness. That s why your finger feels cold when you touch something cold. The heat is leaving your finger and transferring transferring into the cold object.

  10. When you touch something hot, it burns because the heat is being rapidly transferred to your finger. transferred

  11. When this energy transfer takes place, the cooler object will warm up until the temperatures are equal. Is this an example of conduction, convention, or radiation?
