Applying the 1st and 2nd law of thermodynamics to a cycle, show that it is impossible to build a heat engine with only one heat resevoir (T ext.)
First law : dU=dQ - dW
2nd law : It is impossible for any system to undergo a process in which it absorbs heat from a reservoir at a single temperature and converts the heat completely to mechanical work, with the system ending in the same state in which it began.
Where do I begin and is T ext.?
