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 beA. `380J`B. `500J`C. `460J`D. `300J`

Answer» Correct Answer - C
In cyclic process `Q_(cyclic) = W_(cyclic)`
`Q_(AB)+Q_(BC) + Q_(CA) =` area enclosed
`400+100+Q_(CA) =` area enclosed
`400+100+Q_(CA)=1/2xx(4xx10^(4)xx2xx10^(-3))`
`Q_(AC) = 500-40J = 460J`.
