A carnot engine working between 200k and 400k has a work output of 600 J per cycle. How much heat energy is supplied to the engine from the source of each cycle.
Correct answer: B. 1200 J
- A. 1400 J
- B. 1200 J
- C. 1700 J
- D. 1300 J
Explanation
T₁ =400kT₂-200kW=800JWe know efficiency=1-T2/T1-WW/Q=1-200/400=600/0.5=1200JAs it is numerical, it can have only one answer.
