Thanks Resnick for your time and quick replies. I enjoy learning about physical chemistry and hopefully later I will contribute back to this forum.

Ok I think I understand. My problem was: how can there be heat if there is no temperature difference, and your answer is that it is evolved from work. Sorry I'll stop after this question. Where is the heat coming from when work is done? What happens is the microscopic level when work is done...

What I think I understand so far: Internal energy is the sum of work done on a system and heat supplied to the system. In an isothermal case there is no change in temperature therefor internal energy has no change. therefor -q=w Question: Why is there heat? I thought heat is the energy...
