Answer:
Step-by-step explanation:
Work out can never be greater than work in because when work out is greater than work in, this means that more energy is being produced than what is being put into the system. This is not possible, as it would violate the law of conservation of energy, which states that energy cannot be created or destroyed, only transformed.
If work out were greater than work in, this would lead to an increase in efficiency, as the system would be able to produce more energy than what is being put into it. However, this increase in efficiency would be unsustainable, as it would eventually lead to an energy imbalance and a decrease in efficiency over time.
