热力学第二定律习题
A system absorbs 473 J of heat reversibly from a hot reservoir at 529 K and gives off 182.1 J of heat to a cold reservoir at 213 K.During this process,124.6 J of work is done by the system
从热源中吸收473J热量可逆,温度为529K,释放了182.1J的热量给冷物体,温度为213K,在这个过程中,做了124.6J的功.
求这个过程中1.内能变化J 2.熵的变化J/K 3.宇宙熵的变化

内能的变化是：
473-182.1-124.6
这里,系统熵的变化：529K的热源放热Q1=473,熵变是-473/529,213K的热源的熵变是正的,182.1/213,两者的和就是总熵变.
然后宇宙熵变是0.因为这是可逆过程.
