PhysicsEnergyGCSEAQA Created by: Ami_BullCreated on: 15-04-14 16:17 Transfer of energy by heating without the substance moving CONDUCTION 1 of 15 A material that have few or no free electrons so they are bad conductors. INSULATOR 2 of 15 A very good conductor METAL 3 of 15 Transfer of energy by heating through the movement of particles CONVECTION 4 of 15 Convection: Particles closer to the source move faster, causing the substance to expand and become.... LESS DENSE 5 of 15 Convection: The warm liquid/gas rises and cools. Then it becomes more dense and... SINKS 6 of 15 Convection: The colder denser liquid moves into the space created and the cycle repeats this is known as a... CONVECTION CURRENT 7 of 15 Conduction: As metals become hotter the atoms _______ more vigorously. VIBRATE 8 of 15 Conduction: The additional energy is transfered to the cooler parts of a metal by.... FREE ELECTRONS 9 of 15 Evaporation: The transfer of energy at the surface of a liquid EVAPORATION 10 of 15 Evaporation: Atoms closer to the surface of the liquid move faster and... ESCAPE 11 of 15 Evaporation: The overall energy in the atoms... REDUCES 12 of 15 Evaporation: The result is a fall in... TEMPERATURE 13 of 15 What is the gas that is the result of evaporation? WATER VAPOUR 14 of 15 What is the opposite to evaporation? CONDENSATION 15 of 15
