Chemical Engineering Thermodynamics

Pick out the wrong statement.

  • A. A refriferation cycle violates the second law of thermadynamics
  • B. Refrigeration cycle is normally represented by a temperature vs. entropy plot
  • C. In a refrigerator, work required decreases as the temperature of the refrigerator and the temperature at which heat is rejected increases
  • D. One ton of refrigeration is equivalent to the rate of heat absorption equal to 3.53 kW
Answer: Option A.

Since refrigeration cycle works by taking some help or work from the surrounding to transfer heat from low temperature reservoir to high temperature reservoir it is following the second law of thermodynamics namely Clausius statement.
