Thermal Conduction

HideShow resource information

1) Conduction:

mode of heat transfer

from hot end to cold end

from particle to particle of medium

Where it takes place usually:

in solids

Why it is not possible in vacuum:

it requires medium

Explain Conduction:

heat one end of solid

atoms at heated end absorb energy

so they vibrate without leaving mean position

pass extra energy to neighbouring atoms

neighbouring atoms gain energy- start to vibrate

process continues till entire arrangement of atoms start to vibrate

So what?

Heat is transferred from hot end to cold end
