A cyclic process for an ideal gas is shown in figure . Given `W_(AB) = +700 J , W_(BC) = +400J , Q_(CA) = -100J`.

Find `W_(CA)`

A

`-500J`

B

`500J`

C

`400J`

D

`-400J`

Text Solution

Verified by Experts

The correct Answer is:
A
For complete cycle `Q =W`
`implies Q_(AB) + Q_(BC) + Q_(CA) = W_(AB) + W_(BC) + W_(CA)`
`implies 700+ 0 + (-100) = 700 + 400 + W_(CA)`
`implies W_(CA) = -500J`
