Calculate the Change in Internal Energy (ΔU) for a System

Calculate the change in internal energy (ΔU) for a system that is absorbing 35.8 kJ of heat and is expanding from 8.00 to 24.0 L in volume at 1.00 bar. (Remember that 100 J = 1 L bar)

A) +51.8 kJ
B) -15.8 kJ
C) -16.6 kJ
D) -29.3 kJ
E) +34.2 kJ
