please answer these questions 1. What is the difference between a refrigerator and a heat pump? 2. A heat pump and a refrigerator are operating between the same two thermal reservoirs. Which one has a higher COP? 3. Define the COP of a heat pump. 4. Thermal efficiency of a heat engine is defined to be the ratio of energy output desirable to energy input. Would you think that efficiency is an appropriate definition to be used when a heat...

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...

please help me, how could solve these problems
In chemical kinetics and other types of rate processes, you frequently encounter with the initial condition m(0) == 2 6-4 B representing the interconversion of two species, A and B. The the scheme A rate equation for this interconversion can be written as dA/dt = -k\A + kąB, where k and kz are called rate constants. By conservation of mass, A(t)+B(t) = AoBo, where Aq = A(0) and Bọ...
