标题[热能] 等温压缩
时间Wed May 30 09:40:03 2007
Three moles of an ideal gas undergo a reversile isothermal compression
at 20C. During this compression, 1850J of work is done on the gas.
What is change of entropy of the gas?
应该是-1850/293对吧
可是Young的解答写1850/293耶
是我错了吗?
谢谢^^

1F：推 weakaday:因为气体是吸热，所以Q取正~~~~ 05/30 10:54
2F：推 pobm:可是被压缩是外界对气体作功耶 05/30 13:24
3F：→ pobm:1850J of work is done on the gas.是不是我文法太烂~~ 05/30 13:24
4F：→ pobm:我看起来他好像是在说气体被做功1850J 05/30 13:25
5F：推 weakaday:这句翻出来似乎是1850J的功被做在气体上...我英文也很破 05/30 16:07
6F：推 weakaday:pobm你的答案应该是对的，解答可能有错 05/31 09:54
7F：→ weakaday:我之前忘记考虑热力学第一定律了 05/31 09:58
