The volume of a gas decreases from [IMAGE] to
[IMAGE] when a sample of gas is compressed by an average
pressure of 0.6 atm. During this process 10 of heat is liberated. The
change in internal energy is
Show answer and solution
Here t Change in
[IMAGE] Pressure (P) = 0.6 atm and heat liberated (q)=10 J
But 1 liter-atm = 101.3 J
Hence [IMAGE]. We also know that heat is liberated,
therefore it would be negative. Thus change in
