Flashcards in Heat Deck (8)
(Solids) vibrating particles pass on extra kinetic energy (heat) to neighbouring particles
(liquids and gases) liquid and gas particles are free to move. Particles with more kinetic energy move from hotter to cooler regions taking their thermal energy with them.
Heat energy travels in waves
Doesn't need particles
Metals are good conductors of heat. Copper is one of the best and is used in wiring and pipes
Plastics, polystyrene and air are poor conductors and are used as insulators to keep heat in.
Process by which a liquid becomes a gas. Evaporation takes thermal energy away from the surface on which it is occurring
Particles move further a part due to more kinetic energy
Process by which a gas becomes a liquid
Particles move closer together they have less kinetic energy
