Karten in diesem Stapel (16)
- 1HeatMeasure of energy
- 2Temperaturemeasure of hotness of a body on an arbitrary scale
- 3Specific Heat Capacity (SHC)the amount of energy needed to raise the temperature of 1 kg of substance by 1 degree Celcius
- 4Specific Latent Heat SHLthe amount of energy needed to change the state of a substance without changing its temperature
- 5Conduction of Heatprocess where vibrating particles pass on extra kinetic energy to neighbouring particles
- 6Convectionwhen more energetic particles move from the hotter region to the cooler region and take their heat energy with them
- 7Radiationthermal energy transfer which occurs when something hotter than its surroundings radiates heat from its surface
- 8Ways to save energy...Loft Insulation, Cavity Walls and insulation, Draught-proofing, Thick curtains, Double glazing, hot water tank jacket
- 9Efficiencyratio of useful energy output to total energy input. also expressed as a %
- 10Amplitudedisplacement from the rest position to the crest
- 11Wavelengthlength of the full cycle of wave - from crest to crest
- 12Little diffraction is when...gap is much wider than wavelength
- 13Diffractionthe spreading of a wave when it passes through a gap or around an edge
- 14Refractionchange in speed & usually direction, when light passes through from one medium to another: air to water
- 15S wave travel through...solids only
- 16P waves travel....through solids and liquids
