Conversely, heat flow out of the system or work done by the system (on the surroundings) will be at the expense of the internal energy, and q and w will therefore be negative. While the subject of thermal conduction is an important one, and obviously a proper topic in the theory of heat, it is not really part of the great logical structure of thermodynamics, not does it require a wide or deep knowledge of thermodynamics to understand it, at least at an introductory level. 7. One way to generalize the example is to consider the heat engine and its heat reservoir as parts of an isolated (or closed) system—i.e., one that does not exchange heat or work with its surroundings. 2. 15.
