A heat pump in heating mode extracts 1,067 J from the cold reservoir while transferring 1,365 J to the hot reservoir. Calculate its coefficient of performance.
Added by Trevor G.
Step 1
The COP is defined as the ratio of the heat delivered to the hot reservoir (Q_h) to the work input (W) required to transfer that heat. The formula is: \[ COP = \frac{Q_h}{W} \] Show more…
