First Law of Thermodynamics
... Introduced the idea of internal energy. All of the energy of the system. Discussed that the internal energy is a state function. That is that it only depends on the state of the system (its particular properties T,V,P, ...) not how the system arrived in this state. Changes in internal energy are the ...
