Question
Curve in the figure shows an adiabatic compression of an ideal gas from 15 m3 to 12 m3, followed by an isothermal compression to a final volume of 3.0 m3. There are 2.0 moles of the gas. Total heat supplied to the gas is equal to : (ln2 = 0.693)
Options
A.4521 J
B.− 4521 J
C.− 6654 J
D.− 8476 J
Solution
There is no heat transfer in adiabatic compression. In isothermal process
Q = W = P1V1 ln
= 400 × 12 ln
= − 6654 J
Q = W = P1V1 ln
= 400 × 12 ln
= − 6654 J Create a free account to view solution
