The correct answer is: Work is done on the system.
Since the internal energy of the system decreased by -230 kJ, this means that the system lost energy. If the system also released 300 kJ of energy, it means that some of this energy was lost as heat, and some was used to do work. Therefore, work was done on the system to account for the additional energy loss.
The internal energy ∆E of a system is -230 kJ. If the system released 300 kJ, How much work was done in the system? Based on your answer, one of the following answer is correct.
Heat flow is constant
Work is done on the system
The system does work
It is a process were heat flow from the surrounding to the system
