Question: What is the efficiency of a Carnot engine operating between temperatures T1 and T2? (2019) 2019

Options:

  1. (T1 - T2) / T1
  2. T2 / T1
  3. (T1 - T2) / T2
  4. 1 - (T2 / T1)

Correct Answer: 1 - (T2 / T1)

Exam Year: 2019

Solution: 

The efficiency (η) of a Carnot engine is given by η = 1 - (T2 / T1), where T1 is the higher temperature and T2 is the lower temperature.

Questions & Step-by-Step Solutions

What is the efficiency of a Carnot engine operating between temperatures T1 and T2? (2019) 2019
  • Step 1: Identify the two temperatures involved in the Carnot engine. T1 is the higher temperature and T2 is the lower temperature.
  • Step 2: Write down the formula for the efficiency of a Carnot engine, which is η = 1 - (T2 / T1).
  • Step 3: Substitute the values of T1 and T2 into the formula.
  • Step 4: Perform the division of T2 by T1.
  • Step 5: Subtract the result from 1 to find the efficiency (η).
