5.A.1 Thermodynamic system, state function
Thermodynamics is the study of energy and its relationship to macroscopic (i.e. large-scale, non-relating to molecular) properties of chemical systems. Why do I say large-scale? Because thermodynamic functions is based on probabilities, which require a LARGE sample. In statistics, we need large samples, because for example Miley, if I wanted to investigate “how many girls think Jeremy is cute”, I wouldn’t investigate only YOU, because CLEARLY we know you think I am hehe We need a sample, a large sample, which is “representative” of the population. Generally, a sample of sqrt(n) represents a population of n.
