How is a change in internal energy equal to a change in entropy?

Lavelle’s main point was that they are equal because there is no change in volume!

This is a bit of a manipulation of our equation Delta u = q + w. If we know that there is a constant volume, we can assume there is zero work. As such, delta u = qp. We learned that qp is the same as delta H so u = delta H.

If there is a constant volume that would mean that the internal energy would be equal to 0 in which q+w = u would actually be q +w = 0 in which heat and the work performed on the system are equal.
