1 litre of a gas at STP is expanded adiabatically to 3 litre. Find work done by the gas. Given `gamma` = 1.40 and` 3^(1.4)= 4.65 `

A

`111.1J`

B

`221.1J`

C

`321.1J`

D

`411.1J`

Text Solution

Verified by Experts

The correct Answer is:
A
`W= n RT_(0)l n3`
`= P_(0) V _(0) l n 3J " "= 1.01 xx 10^(5) xx 10 ^(-3)xx ln 3J`
`=101xx1.1J" "=111.1J`
