1莫耳真實氣體遵守PV=RT+bP的狀態方程式,且Cv與溫度無關,
b是正常數,且V2>V1,已知Cp=Cv+R,要求ΔSsys、ΔSsurr、ΔSt
(1)此氣體從(T1, V1)經絕熱可逆膨脹(adiabatic reversible expansion)
到(T2, V2)
(2)此氣體從(T1, V1)經絕熱自由膨脹(adiabatic free expansion)
到(T2, V2)
第1小題沒問題,通通為零,想請問第2小題
絕熱的話Qsurr=O 所以ΔSsurr=O、此題為真實氣體所以
ΔSsys是用全微分展開來算嗎? 算出來ΔSt>0是否正確
(覺得是不可逆絕熱所以ΔSt>0)還是有另外算法?
另外第4小題此氣體從(T, V1)經等溫可逆膨脹到(T, V2)的ΔSsurr如何算才好
問題有點煩雜!!煩請大家幫忙了!!謝謝
