Question

Which of these best describes heat transfer through conduction?

Answer 1

I'd go for D here. It also fits in with the idea of thermal expansion - as something is heated up, molecules vibrate and maybe collide. they vibrate with bigger amplitudes, so taking up more space, so expanding. maybe

Answer 2
