Chapter 1 Thermodynamics
... To show the equality of the two statements it will be useful to define a heat engine. Heat engine is a system which undergoes a cyclic transformation that takes heat Q1 from a warmer reservoir, converts some of it to work W and rejects the rest Q2 = Q1 ≠ W to a colder reservoir. In contrast, refrige ...

Recall that "specific heat" is a somewhat misleading term that dates back to the time when heat was viewed as a fluid that could be held by a material, hence terms like specific heat, heat capacity, etc. Today we know that "heat" and "work" should always be understood as "heat transfer" and "work tr ...
