What's the difference between
1) deltaU= q+w
and
2) deltaU= deltaH -PV
Is the second equation only for constant pressure? Are there certain circumstances to use each equation or are they interchangeable?

Re: U:Internal Energy
They are essentially the same. It just depends which values you are given in the question, and which you can plug into the equation.

They can both be used to find delta U depending on what's given in the problem. We also went over that when there is no volume change (in most of biology) then delta U = delta H.

They are basically the same, you just pick which one you use based on what information you are given in the question.

Essentially they are the same equation you would just use one or the other depending on the information that is given in the problem.
