During the adiabatic expansion of 2 mole...

During the adiabatic expansion of 2 moles of a gas, the internal energy of the gas is found to decrease by 2 joules , the work done during the process on the gas will be equal to

A

`-2 J`

B

`2 J`

C

`-1 J`

D

`1 J`

Text Solution

Verified by Experts

The correct Answer is:
a
`dQ = - 2 + dW " and " dQ = 0 `
`rArr dW = 2 J = ` work done by the gas
` :. ` Work done on the gas ` = - 2 J`.
