A closed system of 122 moles of an ideal gas with constant-pressure heat capacity of cp = 2.5R expands isobarically from 52°C and 4.9 bar to 137°C, with a thermodynamic efficiency of 0.74.
How much total work is involved in this process?
Please report your answer to the nearest whole kJ and don't forget the sign: "-" if the work is negative, no sign if the work is positive.
