Video Synthesis
- Problem: An ideal gas expands from a pressure of 90 PSIA to 15 PSIA.
- Approach: So for this problem, we want to find the difference in the enthalpy, so we're going to do final enthalpy minus initial enthalpy.
- Key step: Then of course, delta H is going to be final minus initial, the way we talked about so H to minus H1.
- Watch out: And yeah, that's an easy mistake to make.
- Result: And all of that works out to a change and enthalpy of minus 722.2 BTU per pound, which is closest to answer choice B.
- ✅ Answer: C
