  • In refrigerators we have 2 bodies lower temperature (cold) body which is freezer and higher temperature (hot) body which is surroundings.
  • It takes heat from the cold reservoir and then some work is done on the refrigerator and then the amount of heat is transferred to heat reservoir.
  • Let Q2 be the takes from the cold reservoir, W is the work done on the system and then releases Q1 amount of heat to the hot reservoir.
