Hi all,
I am not clear with the concept of "Cooling" a body.I know that the temperature of a body is the average kinetic energy of the molecules or atoms in the body.When heat energy is supplied,the molecules have more vibrations and hence the temperature increases.Let us have two bodies at temperatures t1 and t2 where t2 is less than t1.If they are physically contacted (Let us assume heat transfer takes place purely by conduction).Then how does this heat transfer takes place in molecular level?.How does energy flow take place from body 1 to body 2?.(I know that heat flows from high temperature to low temperature but how?).
