题目是
A 1.00-mol sample of an idea gas in a vessel with a movable piston
initially occupies a volume of 5.00L at an external pressure of 5.00 atm
a. if Pex is suddenly lowered to 2.00 atm and the gas is allowed to
expand isothermally caculate : △E △H △S △G w and q
b. show by the second law that this process will occur spontaneously
我再次回头看了详解 发现它代 q值进去的地方是在△S(univ)=△S(sys) + △S(surr)
这其中有什麽关联吗@@?
