P1 A 0.0 / 5 ? PhysicsEnergyGCSEAQA Created by: rpickstockCreated on: 23-03-15 19:11 What are the three states of matter? Solid, Liquids & Gases 1 of 13 Name the three ways energy is transferred. Infrared radiation (IR), Conduction & Convection 2 of 13 What absorbs IR better Dark, matt or Light, shiny surfaces? Dark, matt surfaces 3 of 13 What is the main form of heat transfer in solids? Conduction 4 of 13 What is the main form of heat transfer in Liquids & Gases? Convection 5 of 13 What can Infrared radiation be emitted by? Solids, Liquids and Gases 6 of 13 Conduction and convection involve the transfer of energy by what? Particles 7 of 13 What happens during conduction? The heat particles vibrate and pass their extra kinetic energy to their neighboring particles 8 of 13 What is a good conductor? Why Metals. They have free electrons 9 of 13 What happens during convection? The more energetic particles move from the hotter region to the cooler region - taking their heat energy with them. 10 of 13 What happens in terms of states of matter & particles during condensation A gas cools and the particles slow down and lose kinetic energy. If it gets cold enough the particles condense. Becoming a LIQUID 11 of 13 What happens in terms particles during evaporation? It is when particles escape from a liquid. 12 of 13 What are the rules for evaporation? The particles have to be travelling in the right direction and fast enough. 13 of 13
