Direction of vibration of molecule with respect to transfer of heat

  • #1

Main Question or Discussion Point

the heat causes the molecule to vibrate.how does the molecule vibrate in terms of angle formed by vibrating molecule and the direction of tranfer of heat in conduction, convention and radiation?

That would be really difficult to answer at individual molecule/atom level for conduction. If you are looking at conduction in metals, you should be worried more about movement of electrons which forms a major part of heat transfer and molecular vibration only a little. Having said that, the individual molecules may vibrate in directions other than the direction of heat transfer but the net movement will be in the direction of heat transfer (remember heat transfer is never in one direction - it is always 3 dimensional when you are looking at molecular level)
