Ammonia gas is condensed at its boiling point at 1.01325 bar at -33.4℃ by
the application of a pressure infinitesimally greater than 1 bar. To
evaporate ammonia at its boiling point requires the absorption of 23.3 kJ
mole-1. Calculate (a) Wrev per mole, (b) q per mole, (c) △U, and (d) △H.
我实在不太了解题目在说什麽
我是觉得他说以每次加极小的压力去加压Ammonia气体使他冷凝
是一个可逆过程
压力每点都平衡在1.01325 bar
不知道我的想法对不对

1F：推 saram:ammonia 是冷媒, condense是冷凝(将高压高温冷媒变成高压低 11/18 03:01
2F：→ saram:温的冷媒). evaporete 是蒸发(把低温低压的液态冷媒借热蒸 11/18 03:03
3F：→ saram:发成低压常温的冷媒) 11/18 03:04
