### 8.5

So whenever we are trying to find the change in internal energy, we add the two energy terms?

In this question's case, yes. In general, the change in internal energy can be found by adding the two energies, while paying attention to the signs on the energy changes.

Yes, the for the change of internal energy is:
$\Delta U$=q (heat) + w (work)
