1 4.2 How Does Heat Move?

2 4.2 How Does Heat Move? What is convection?

3 4.2 How Does Heat Move? What is convection?
Transfer of heat through the motion of gasses and liquids such as air and water

4 4.2 How Does Heat Move? What is convection?
Transfer of heat through the motion of gasses and liquids such as air and water Warm air rises

5 4.2 How Does Heat Move? What is convection?
Transfer of heat through the motion of gasses and liquids such as air and water Warm air rises Cold air sinks

6 4.2 How Does Heat Move? What is convection? What is conduction?
Transfer of heat through the motion of gasses and liquids such as air and water Warm air rises Cold air sinks

7 4.2 How Does Heat Move? What is convection? What is conduction?
Transfer of heat through the motion of gasses and liquids such as air and water Warm air rises Cold air sinks Transfer of heat by the direct contact of atoms and molecules in solids

8 4.2 How Does Heat Move? What is conduction?
Transfer of heat by the direct contact of atoms and molecules in solids Transferred from atom to atom by direct contact

9 4.2 How Does Heat Move? What is conduction? What is radiation?
Transfer of heat by the direct contact of atoms and molecules in solids Transferred from atom to atom by direct contact

10 4.2 How Does Heat Move? What is conduction? What is radiation?
Transfer of heat by the direct contact of atoms and molecules in solids Transferred from atom to atom by direct contact Transfer of heat through empty space

11 4.2 How Does Heat Move? What is radiation? Transferred from atom to atom by direct contact Transfer of heat through empty space occurs without direct contact or movement of atoms

12 4.2 How Does Heat Move? What is radiation?
Transfer of heat through empty space occurs without direct contact or movement of atoms All 3 forms of heat transfer can work at the same time to transfer heat from warmer to cooler objects
