In (figure). shows two path that may be taken by a gas to go from a state A to state C

In the process AB, `400 J` of heat is added to the system and in process Bc, `100 J` of heat is added to the system. The heat absorbed by the system in the process AC will be

A

`500 J`

B

`460 J`

C

`300 J`

D

`380 J`

Text Solution

Verified by Experts

The correct Answer is:
B
In cyclic process ABCA
`DeltaU_(cyclic)=0`
From first law of thermodynamics
`Q_(cyclic)=W_(cyclic)+U_(cyclic)`
`:. Q_(cyclic)=W_(cyclic)`
`Q_(AB)+Q_(BC)+Q_(CA)=` closes loop area
`400+100+Q_(CA)= 1/2(2xx10^(-3))xx4xx10^(4)`
`500-Q_(AC)=40 [:. Q_(CA)= -Q_(AC)`
`Q_(A)= 4600 J`
