Two moles of a gas is expanded to double...

Two moles of a gas is expanded to double its volume by two different processes. One is isobaric and the other is isothermal. If `W_(1)` and `W_(2)` are the works done respectively them

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_(i)log_(e )(2)`
