Question 1.: A sample of 6.25 kilograms of water at 7.00°C is placed in the freezer. Assuming all energy removed from the freezer is removed from the water, how long does the 1/5 horsepower (HP) motor(1 HP = 746 Watts) have to run to cool all of the liquid to ice at 0.00°C? The freezer has a COP of 5.00.Your challenge: come up with a complete equation solved for the variable in question before you plug in any of the numerical values given above. In this way, you will be prepared to solve for any of thevariables!Some questions to consider along the way ...(a.) What is the relationship between power, P (in watts) and work, W (in joules)? What is the variable you are eventually solving for?(b.) What is the relationship between the COP a freezer/refrigerator, and work?(c.) How much energy as heat must be removed from the water to freeze it? What heat pump/refrigerator variable does this value correspond to?freezer run time =S =minutes
