Question

Using a timer and a thermometer, conduct the following experiment to determine the rate of heatgain of your refrigerator.1. First, make sure that the door of the refrigerator is not opened for at least a few hours so thatsteady operating conditions are established.2. Start the timer when the refrigerator stops running and measure the time T1 it stays offbefore it kicks in.3. Then, measure the time T2 it stays on.Determine the average rate of heat gain for your refrigerator, in W.Note: Take the coefficient of performance of your refrigerator to be 1.3, please solve if t1 is 2000 seconds and t2 is 800 seconS and a value if P being 600 watts
