This extra work could be used to run a generator, which in turn could be used to produce more heat, which could run more of process, producing even more excess work, and so on. Th ...

Entropy, a statistical approach

This is true for any state function. o If a system has possible microstates then doubling the size of the system will double the entropy (by increasing the number of poss ...
