Worked practice questions

A perfect refrigerator is denied by the statement due to:

  1. Carnot now
  2. Joule now
  3. Clausius
  4. Fowler now
Show answer and solution

Correct answer: C. Clausius

1. One statement denies a perfect engine. 2. The other denies a perfect refrigerator or heat pump. 3. That second one is due to Clausius. _Source: syllabus Physics Part II, Chapter 12, Thermodynamics._
