earning Goal: To understand that a heat engine run backward is a heat pump that can be used as a refrigerator. By now you should be familiar with heat engines--devices, theoretical or actual, designed to convert heat into work. You should understand the following: Heat engines must be cyclical; that is, they must return to their original state some time after having absorbed some heat and done some work). Heat engines cannot convert heat into work without generating some waste...

During each cycle, a heat engine operating between two heat reservoirs absorbs 156 J from the reservoir at 100°C and releases 136 J to the reservoir at 20°C. (a) What is the efficiency of this engine? % (b) What is the ratio of its efficiency to that of a Carnot engine working between the same reservoirs? This ratio is called the second law efficiency. εengine / εCarnot =
