The Four Laws of Thermodynamics
... four laws are and how they work, using accessible language and virtually no mathematics. Guiding the reader a step at a time, Atkins begins with Zeroth (so named because the first two laws were well established before scientists realized that a third law, relating to temperature, should precede them– ...

... You may have noticed that the term “system” keeps cropping up. It is necessary, therefore, that before we start any analysis we define the system that we are looking at. To do this we construct an imaginary boundary around what we are interested in – for example, the cricket ball (struck by Nasser H ...
