The P-V diagram of a system undergoing thermodynamic transformation is shown in figure. The work done by the system in going from A → B → C is 30 J and 40 J heat is given to the system. The change in internal energy between A and C is -
Text Solution
Verified by ExpertsThe correct answer is:
A
Since, work is done by the system, so it is positive. Therefore,
Heat given to the system,
According to first law of thermodynamics, change in internal energy is given by
