what surfaces absorb heat best?
dark, matt e.g.. matt black
5 of 8
what happens during conduction of heat?
vibrating particles pass on their extra kinetic energy to neighbouring particles
6 of 8
why are metals good conductors?
they have electrons that are free to move around inside the metal
7 of 8
how does convection occur?
more energetic particles move from hotter regions to cooler regions taking the heat energy with them
