One mole of an ideal monoatomic gas is heated at a constant pressure of 1 atmosphere from `0^(@)`C to `100^(@0`C. Work done by the gas is

A

`8.31xx10^(3)J`

B

`8.31xx10^(-3)J`

C

`8.31xx10^(-2)J`

D

`8.31xx10^(2)J`

Text Solution

Verified by Experts

The correct Answer is:
D
dW= dQ -dU
`=C_(p)(T_(2)-T_(1))-C_(v)(T_(2)-T_(1))`
`=R(T_(2)-T_(1))`
= `8.31xx100`
= `8.31xx10^(2)J`
