energy transfer 0.0 / 5 ? PhysicsEnergyGCSENone Created by: Frederic ChopinCreated on: 24-06-20 01:25 what are the units for measuring energy joules 1 of 15 if you leave a cup of hot tea standing in the kitchen for a whole day, what will happen energy will be transferred from the tea to the air until the tea is the same temperature as the air 2 of 15 which statement about evaporation is not true when some of a liquid evaporates the liquid left is warmer than before 3 of 15 infrared radiation can travel through empty space and transparent materials 4 of 15 when one of a piece of metal is heated the particles vibrate more and the vibrations are passed from particle to particle 5 of 15 solids are better heat conductors than liquids or gases because the particles are closer together in solids 6 of 15 why does cold air near an ice lolly move downward it is colder and denser than the air further away from it 7 of 15 which statement is the best explanation for why many insulating materials contain trapped air gases are poor conductors and they cannot transfer energy by convection if they cannot move 8 of 15 the surface of which material would reflect infrared radiation the best white and shiny 9 of 15 which statement is correct dark colours are good emitters and absorbers of radiation 10 of 15 what are the units for measuring power watts 11 of 15 how can you find the power of an appliance look for the power rating on the label 12 of 15 the efficiency of an appliance is calculated by comparing the useful energy transferred to the total energy supplied 13 of 15 what units for energy are used on electricity bills kilowatt-hours 14 of 15 what does 'payback time' mean the time it takes to save enough money on energy bills to pay for a change 15 of 15
