[題目] 熱力學第一定律的題目
[領域]熱力學第一定律 (題目相關領域)
[來源]Ashley h. carter 的 classical and statistical thermodynamics
[題目]3-4 Ice at 0度C and a pressure of 1 atm has a density of 916.23kgm^-3
while water under these conditions has a density of 999.84 kgm^-3. How much
work is done against the atmosphere when 10 kg of ice melts into water?
[瓶頸]
我的想法是利用上次大大教我的回到定義去
所以 W=積分PdV =(1.01*10^5)(1.0002*10^-2 - 1.0914*10^-2)=-9.2112*10^3
但是答案是-92J 不知道錯在哪了
麻煩大家幫幫忙吧 謝謝
