PhysicsInteger+4 / -1Question 51 of 90

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 reservior to sink is 12000 kJ, the quantity of heat absorbed by the engine from reservoir is ______ $\times10^6$ J.

Your answer

Answer and worked solution

Official answer: 16

Efficiency. $1-\dfrac{200}{800}=0.75$ .

Heat absorbed. $\dfrac{12000\text{ kJ}}{0.75}=16000$ kJ $=16\times10^6$ J.

Answer: 16

Topics:Carnot cycle
