An ideal gas is taken through cycle `A to B to C-A`, as shown in Fig. IF the net heat supplied to the gas in the cycle is 5 J, the work done by the gas in the process `C to A` is

A

`-5J`

B

`-10J`

C

`-15J`

D

`-20J`

Text Solution

Verified by Experts

The correct Answer is:
A
For cyclic process, `Q_("cyclic") =W_(AB) + W_(BC) + W_(CA) = 10J + 0+W _(VA) 5J rArr E_(CA) = -5J`.
