Heat Definitions
Karten in diesem Stapel (30)
- 1HeatA form of energy which can be transformed. It is the total kinetic and potential energies of the particles that make up the object
- 2TemperatureA measure of the average kinetic energy of the particles that make up a substance
- 3JouleThe unit for energy
- 4CelsiusA temperature scale based around the melting and boiling points of water
- 5KelvinA temperature scale that starts from absolute zero
- 6HotterA term used to describe an object with greater temperature/average kinetic energy of its particles
- 7ColderA term used to describe an object with lower temperature/average kinetic energy of its particles
- 8Change Of StateAdding or removing heat changes the kinetic energy of the particles and can cause the object to move form one state to another
- 9Thermal ConductorAn object that allows heat to flow through it
- 10Thermal InsulatorAn object that restricts the flow of heat through it
- 11ConductionThe heat transfer process which occurs because objects are touching
- 12ConvectionThe heat transfer process that occurs because objects are fluid/can move
- 13RadiationThe heat transfer that occurs without the need for particles/can travel through a vacuum
- 14VacuumA region with no particles
- 15DensityThe mass per unit volume of a substance
- 16Convection CurrentThe flow of particles due to the heating and cooling of the object
- 17SolidParticles packed tightly together in a fixed position. They are gently vibrating, but are held together by strong forces
- 18LiquidParticles are moving and can slide past each other. They are held together by weaker forces and not in a fixed pattern
- 19GasParticles are spaced far apart and move about very quickly. The forces trying to hold them together cannot overcome their rapid movement
- 20MeltingParticles gain kinetic energy and spread out/vibrate more to go from a solid to a liquid
- 21EvaporatingParticles in a liquid gain more kinetic energy and therefore take up more room and turn into a gas
- 22SublimationA solid turns to a gas state without change to a liquid
- 23FreezingA liquid turns to a solid because of a sudden loss of kinetic energy to the particles
- 24CondensationA gas turns to a liquid state
- 25DepositionA gas turns to a solid state without changing to a liquid
- 26Specific Heat CapacityThe amount of energy needed to change the temperature of 1kg of the substance by 1 degree c
- 27Latent Heat of VaporisationUsed for changes between liquid and gas (evaporating/condensing)
- 28Latent Heat of FusionThe amount of energy used for changes between solid and liquid (melting/freezing)
- 29Latent HeatHow much heat energy is absorbed or released when a substance changes state without changing temperature
- 30PowerA measure of the rate of heat energy absorbed or released when a substance changes temperature
