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

`-5 J`

B

`-10 J`

C

`-15 J`

D

`-20 J`

Text Solution

Verified by Experts

The correct Answer is:
a
`DeltaW = W_(AB) + W_(BC) + W_(CA) = 10 + 0 + W_(CA)`
` 5 = 10 + W_(CA) rArr W_(CA) = - 5J`
