Enthalpy question
It's been a while since I thought about this, and I'm too lazy to go find my thermodynamics text book, so could someone remind me why water/steam at
1) 180 psia and 373.1°F, and 2) 32.75 psia and 317.5°F both have an enthalpy of 1197.3 Btu/lbm*°R? |

triple point or critical point ?
One of your values is the same as critical point vs critical pressure for water. Oooops, I hit the submit button too soon. I needed to add: "I really don't have a clue" |

I'm glad you found your answer.
Like I said, I really didn't have a clue. It's been more than 50 yrs since I took PhysChem |

IM, I have the same problem.
I have more empathy for entropy than for enthalpy. I used to work on the 3rd floor and the ice machine was in the basement. I would tell people I was going to get some negative entropy. |

Let's recap: you have more empathy for entropy than you do for enthalpy, in fact, one might say that when it comes to enthalpy you feel apathy. Sorry if I'm being pithy.

Not at all pithy. Maybe our enthalpy is just reaching supercritical.

I once posed this riddle to my friends:
What is the opposite of entropy?
