Okay, getting some input on this question will finish up the last of the Confusing Questions of the latest Chapter Review.
Q: Which involves the larger number of calories?
(a) the condensation of 1 g of steam at 100 C to 100 C water.
(b) the change of phase of 1 g of 100 C water to 1 g of ice AT ABSOLUTE ZERO (emphasis mine)
(c) both involve the same number of calories.
Well, from trying to figure it out, I thought (a) took approx 540 calories and (b) took (or rather releases?) 80 calories, and then I noticed the bit about absolute zero. I must really be confused, because I thought that was Kelvins. I thought the world would shrink out of existence if something went to absolute zero. I thought everything would stop and all the squirrels would fall out of the trees. Which, btw, is why I wish physicists would stop trying to get it down that far. I don't particularly want my last sight on this Earth to be a poor dead squirrel falling onto my soon-to-be dead head. Or is absolute zero just another way of saying 0 degrees C in this case?
Thanking you in advance for any help.
