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 flow formed from temperature differences. I'm confused as to what heat is and why it is not effect in an isothermal case.
Background: first semester in physical chemistry
