The efficiency of a Carnot engine depends upon

Options

  1. Athe temperature of the sink only
  2. Bthe temperatures of the source and sink
  3. Cthe volume of the cylinder of the engine
  4. Dthe temperature of the source only

Correct answer

B. the temperatures of the source and sink

Step-by-step solution

First, recall the formula of efficiency of Carnot engine in terms of source temperature and sink temperature, η = 1 - T 2 T 1 , here the temperature of the source is always higher than the temperature of the sink but when we change source and sink temperate then the efficiency will change, T 1 = the temperature of the source and, T 2 = the temperature of the sink.
