A refrigerator has a coefficient of performance equal to 6.4. If the refrigerator absorbs 200.5 J of thermal energy from a cold reservoir in each cycle, find the work done on the system each cycle (in J). Enter a number with one digit behind the decimal point.Refer to the heat engine experiment in Lab 10. The PV diagram for one cycle of the engine is shown below. -3 -2 -1 ' 1 2 3 4 5 E T 3 9 1|] 11 l'.|12 13 .03 volumeicm') ' (044) \"Hmw . . (3) The path on the diagram connection points (3) and (4} corresponds to which part of the cycle? (a) The air chamber is placed into the ice water. The temperature decreases and the gas contracts. The volume of air in the chamber decrease. (b) A mass is placed on the platform. The weight of the mass increases the pressure at constant temperature. The volume of air in the chamber decrease. {c} The air chamber is placed into hot water. The temperature rises and the gas expands. The volume of air in the chamber increases (d) The mass is removed from the platform. Removing the weight decreases the pressure at constant temperature, The volume of air in the chamber increases. 0 This path is not part of the cycle. {c} 0 (d) O {a} 0 lb}
