Saucepan have plastic handles because plastics are good conductors of heat.





False : They have plastic handles becuase plastic is a POOR conductor of heat





Houses are painted in hot countries, white so it can reflect radiation and stay cool.





True





When you have double glazing heat can still escape through a window by radiation.





True : Double glazing reduces heat lost by conduction





Heat energy travels to the earth from the Sun by conduction. Once again





False : It gets here by radiation





The particles at the hot end of a metal rod vibrate vigorously.





True





A thick piece of glass is a better insulator than two thin ones with a layer of air between them.





False : Its the air gap that increases the insulation value





When fluids are heated they become less dense and fall.





False : Heated fluids become less dense and RISE





A black car will absorb more radiation than a white car and will therefore remain cooler.





False : It absorbs more radioation (In the sun) and gets HOTTER
