Two refrigerators A and B operate in series. Both refrigerators absorb energy at same rate of 1.5 KJ/s. Refrigerator A absorb energy from a body at temperature 300 K and reject heat to a body at temperature T. Refrigerator B absorb energy from the body at temperature T which is rejected by A and it reject energy to body at temperature 900 K. If both refrigerators have the same COP, then calculate i) Temperature T of the body ii) COP of Refrigerator iii) Rate at which energy is rejected.
