Why can a refrigerator be set on the floor and plugged in?5.) Does a refrigerator full of food consume more power if the room temperature is 20°C than if it is15°C? Or is the power consumption the same? Explain your reasoning.6.) What would be the efficiency of a Carnot engine operating with TH = Tc? What would be the efficiencyif Tc = 0K and TH were any temperature above 0 K? Interpret your answers.
