A gas is expanded to double its volume by two different processes. One is isobaric and the other is isothermal. Let `W_(1)` and `W_(2)` be the respective work done, then find `W_(1)` and `W_(2)`

Text Solution

Verified by Experts

`W_(1)=P_(i)(V_(f)-V_(i))=P_(i)V_(i)((V_(f))/(V_(i))-1)`
`=nRT(2-1)=nRT`
`W_(2)=nRT"log"_(e)((V_(f))/(V_(i)))=nRT "log"_(e)(2)=W_(1)"log"_(e)(2)`
