the amount of work done by the gas system in increasing the volume of 10 moles of an ideal gas from 1L to 20L at 0℃ will be?
A zero
B 3.49J
C 3.49*10^4J
D 6.79*10^4J
这是AS题目=
A zero
B 3.49J
C 3.49*10^4J
D 6.79*10^4J
这是AS题目=
这是等温膨胀过程,系统内能变化为零,系统对气体所做的功等于系统从外界吸收的能量.
做功A= - ∫ p d V（从V1积分到V2）= - νRT ∫ （1/V）dV（从V1积分到V2）
对于10mol理想气体,ν=10,R是摩尔气体常量,T=0℃=273K.
代入上式可得.
再问： 所以答案是什么？
能给全过程吗 、谢谢
