2. Heat Transfer Heat always moves from a warmer place to a cooler place. True or False If you put a hot object in a cooler room, it will cool to room temperature. If you put a cold object in a warmer room will heat up to room temperature.

5. Register continuum L.O:-. WILF is for you to be able to explain how heat energy is transferred. Spoken Everyday language Written Formal language

7. Water movement Hot water rises Cooler water sinks Convection current Cools at the surface

8. Why is it windy at the seaside?

9. Cold air sinks Where is the freezer compartment put in a fridge? Freezer compartment It is put at the top, because cool air sinks, so it cools the food on the way down. It is warmer at the bottom, so this warmer air rises and a convection current is set up.

10. 1. In which of the following are the particles closest together? A.Solid B.Liquid C.Gas D.Fluid

11. 4. Which is the best surface for reflecting heat radiation? A.Shiny white B.Dull white C.Shiny black D.Dull black

12. Convection Plenary questions Using the following keywords answer the questions. I will be asking 2 students to come up and answer them in front of the class and talk like a scientist. 2. Why are boilers placed beneath hot water tanks in people’s homes? Hot water rises. So when the boiler heats the water, and the hot water rises, the water tank is filled with hot water. 1. Why does hot air rise and cold air sink? Cool air is more dense than warm air, so the cool air ‘falls through’ the warm air. Keywords Dense Warm air Falls Rise Sink Cold air
