2. 1 1 Convection When you boil water the lower water layer heats up quickly then it goes up and the upper water layer ( cold ) goes down. This process takes place many times till all water become hot. This movement of water from down to up then to down we call it CONVECTION

3. 1 1 Convection This process takes place also in air like in warming up home by a heater Convection takes place in gases and fluids

4. Sea breeze At morning, land gets hot faster than sea water so the air on the water is cold ( high pressure ) but the air will get hot than rise ( low pressure ). At this time a cold air will move from sea to land ( SEA BREEZE)

5. Land breeze At night, land gets cold faster than sea water which becomes hot. The air on the water will get hot so it will rise ( low pressure). On land, the air still cold ( high pressure). At this time air will move from land to sea ( LAND BREEZE)

6. 2 2 Conduction Heat can be transferred by solids. But at this time particles of a matter don’t carry heat from point to another but heat transferred by touching among the particles of a solid matter. Here we call this CONDUCTION Heat conduction takes place in solids

7. 1 Thermal good conductors 2 Thermal bad conductors

8. 3 3 Radiation Heat can travel in space not only by gases and fluids ( convection ) or by solids ( conduction ) but also in space like heat coming from the sun. Heat radiation takes place in space

9. See the following diagram and summarize the ways by which heat transferred
