In a carnot engine, the temperature of reservoir is 527 ° C and that of sink is 200 K . If the workdone by the engine when it transfers heat from reservoir to sink is 12000 kJ , the quantity of heat absorbed by the engine from reservoir is _____ × 10 6 J .

Correct answer

0

Step-by-step solution

Efficiency of Carnot engine is η = 1 - T L T H = W Q , where, Q is heat absorbed. Here, T H = 527 + 273 = 800   K Now, η = 1 - 200 800 = 12 Q ∴   3 4 = 12000 Q ∴   Q = 16 × 10 6   J
