Final answer:
The coefficient of performance (COP) for a heat pump can be calculated by dividing the heat transfer from the hot reservoir by the work supplied. In this case, the COP is approximately 1.19.
Step-by-step explanation:
The coefficient of performance (COP) for a heat pump is the ratio of heat transfer at the output (the hot reservoir) to the work supplied. It can be calculated using the formula COP = Qout / W, where Qout is the heat transfer from the hot reservoir and W is the work supplied. In this case, Qout = 1,296 J and W = 1,090 J. Plugging these values into the formula, we get COP = 1,296 J / 1,090 J = 1.19.
