An ideal gas is taken through the cycle ...

An ideal gas is taken through the cycle `AtoBtoCtoA,` as shown in the figure, If the net heat supplied to the gas in the cycle is 5J, the work done by the gas in the process CtoA is

A

`-5J`

B

`-10J`

C

`-15J`

D

`-20J`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) For cyclic process,
`Q_(cycle)=W_(AB)+W_(BC)+W_(CA)=10j+0+W_(CA)=5J`
`rArrW_(CA)=-5J`
