An ideal gas is enclosed in a cylinder that has a movable piston on top.The piston has a mass m and an area S and is free to slide up and down,keeping the pressure of the gas constant.How much work is done on the gas which amount of substance is v as the temperature of the gas is raised from T1 to T2?请帮忙给出正确答案和分析,谢谢!

参考答案:Since the pressure of the gas is keeping constant,the work that is done on the gas is simply
A=p(V1-V2)
By using the state equation pV=vRT,we have V=vRT/p,thus

Therefore,as the temperature of the ga360问答s is raised from T1 to T2,the work that is done on the gas is A=vR(T1-T2).
