ScienceEnergy and efficiencyGCSEAll boards Created by: kfgintyCreated on: 31-03-16 15:14 Temperature How hot or cold something is. 1 of 17 Thermometer A device used to measure temperature. 2 of 17 Expansion This is caused by a gain in heat energy, which causes the particles to take up more space. 3 of 17 Conductor Heat energy can easily pass through this material. 4 of 17 Insulator Heat energy cannot easily pass through this material. 5 of 17 Thermal Energy Is transferred from a hot object to a cold object. 6 of 17 Melting point When a solid becomes a liquid. 7 of 17 Freezing When a liquid becomes a solid. 8 of 17 Convection The movement of air and other gases due to heat. 9 of 17 Convectional Currents When hot particles rise, and then fall as they cool down. 10 of 17 Fluids Liquids and gases. 11 of 17 Vacuum There are no particles present. 12 of 17 Radiation Heat energy that moves without a medium. It does not require particles. 13 of 17 Conduction and Convection Both require particles that move, in order to transfer heat energy. 14 of 17 Medium Needed to transfer energy by conduction and convection. 15 of 17 Boiling Point When a liquid becomes a gas. 16 of 17 Condensing When a gas becomes a liquid. 17 of 17
