標題[學科] 一題熱力學
時間Thu Nov 15 15:55:28 2007
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.
我實在不太了解題目在說什麼
我是覺得他說以每次加極小的壓力去加壓Ammonia氣體使他冷凝
是一個可逆過程
壓力每點都平衡在1.01325 bar
不知道我的想法對不對

1F：推 saram:ammonia 是冷媒, condense是冷凝(將高壓高溫冷媒變成高壓低 11/18 03:01
2F：→ saram:溫的冷媒). evaporete 是蒸發(把低溫低壓的液態冷媒借熱蒸 11/18 03:03
3F：→ saram:發成低壓常溫的冷媒) 11/18 03:04
