Document Summary
Start from a trivial/ obvious place the magic of state functions. Property of a system that only depends on its state. There are certain properties that depend only on the instantaneous state of the system. To know how such properties, only need to know the starting point & ending point (initial and final states); particular path that was taken does not matter. Other properties do depend on the path that"s taken. Properties that depend only on the state of the system: state function (altitude) *deep consequence- any conceivable paths between the same two states must produce the same change in any state function (not traversing the path) Can make predictions without doing the experiment or knowing it"s possible. Properties that depend on history: path function (attitude) Microscopically- related to the total energy of molecules // not so useful because you can"t assay molecules in any simple, direct way. The amount of heat is proportional to change in temperature (q is.
