1. Heat is Transferred 3 Ways
Convection –the transfer of thermal energy by movement of currents within a gas or a liquid E.g. Air and ocean current, boiling water
Radiation – transfer of energy by electromagnetic waves E.g. Roasting marshmallows over a fire
Conduction – the transfer of thermal energy between particles within a substance by touch E.g. Getting a burn from picking up a hot pot on the stove

2. Can you identify which type of heat transfer is occurring?

Can you identify which type of heat transfer is occurring?

3. Ben’s breath on a cold day
convection
Convection –The Ben’s breath is circulating in the air

4. Hot cocoa
Convection
Convection –The heat in the hot cocoa is travelling in a current in the cup
Conduction –When your hand touches the cup

5. Soup spoon in hot soup
Conduction
Conduction –Heat transferred from soup to spoon through direct contact

6. A geyser named Geysirs -a hot spring that releases water and hot steam out of the Earth’s surface
Convection
Convection –Hot steam and water are circulating under and above ground in currents

7. Chicks huddling under a heat lamp
Radiation
Radiation –Heat is being transferred by electromagnetic waves (Light energy) via the heat lamp

8. Baking chocolate cake
Convection
Convection –Heat in the oven circulates in currents to bake the cake
Conduction –The woman is transferring heat to her oven mitts

9. Melting ice cream
Conduction –Heat is being transferred from the hand to the ice cream cone causing the ice cream to melt
Conduction

10. Fireplace
Radiation –The room is being heated through electromagnetic waves (light energy)
Radiation

11. Boiling water
Convection –The heat is circulating in a current through the boiling water
Conduction –Heat is being transferred through touch from the hot water directly to the eggs
Convection
