NEET Physics Thermodynamics Questions Solved


Two Carnot engines A and B are operated in succession. The first one, A receives heat from a source at T1 = 800 K and rejects to sink at T2 K. The second engine B receives heat rejected by the first engine and rejects to another sink at T3 = 300 K. If the work outputs of two engines are equal, then the value of T2 is -

(1) 100K

(2) 300K

(3) 550K

(4) 700K
