Questions
The P –V diagram of a system undergoing thermodynamic transformation is shown in figure. The work doneby the gas in going from A→B→C is 50 J and 20 cal heat is given to the system. The change in internal energy between A and C is
detailed solution
Correct option is A
For the proess A - B - C,ΔQ = + 20 × 4.2 J = 84 J.ΔW = +50 JNow, ΔQ = ΔU + ΔW⇒ (+84) = ΔU + (+50)⇒ΔU = 34 J.Talk to our academic expert!
