Energy transfer by heating 0.0 / 5 ? PhysicsEnergyGCSEAQA Created by: howea017Created on: 11-12-13 18:30 Name the 3 ways heat is transferred from place to place Conduction, convection, radiation 1 of 13 Dark matt surfaces are better at absorbing heat than light shiny surfaces, true or false? True 2 of 13 The colder an object is the more infra red radiation it emits, true or false? False, the hotter an object is the more infra red radiation it emits. 3 of 13 Can radiation pass through the vacuum of space? If so, why? Yes it can, because it is a type of electromagnetic radiation that involves waves rather than particles. 4 of 13 Are light shiny surfaces good at emitting and absorbing infra red radiation? No they are poor, black matt surfaces can absorb and emit radiation well. 5 of 13 Explain the arrangement of particles in a solid, liquid and gas. Solid=close together, regular pattern Liquid=close together random Gas=far apart, random 6 of 13 Explain the movement of particles in a solid, liquid and gas. Solid=vibrate around a fixed position Liquid=move around each other Gas=Move quickly in any direction 7 of 13 What are poor conductors of heat known as? Insulators. 8 of 13 As particles are heated, they vibrate more, and spread this heat by passing on their energy, true or false? True 9 of 13 What is kinetic theory? The energy that moving objects have. 10 of 13 When do convection currents occur? hen particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. 11 of 13 What does evaporation involve? liquid changing to a gas. 12 of 13 What is condensation? When a gas cools and condenses into a liquid. 13 of 13
