Heat and Thermal ExpansionHard
Question
The following are the P-V diagram for cyclic processes for a gas In which of these processes is heat absorbed by the gas ?
Options
A.
B.
C.
D.
Solution
Fig A : WA = +ve Fig B : WB = +ve
Fig C : WC = +ve Fig D : WD = -ve
∴ in process Fig - (D), heat is released.
Fig C : WC = +ve Fig D : WD = -ve
∴ in process Fig - (D), heat is released.
