Consider a system changing from state 1 to state 2 reversibly. In order for this change of state to occur, 4.45 kJ of heat is transferred from the system to the surroundings, causing the system to expand from 35.4 L to 62.1 L against a final pressure of 4.63 atm.

Calculate the change in internal energy for the system (U_sys) in kJ.

If the system returned to state 1 reversibly, completing the cycle, what would be TRUEof w_sys,cycle?

Incorrect w_sys,cycle > 0
Incorrect w_sys,cycle < 0
Correct: w_sys,cycle = 0
