WebThe Big Four Thermodynamic State Functions: internal energy (U), enthalpy (H), entropy (S), and free energy (G). All four of these are energy terms. Extensive variables________ on the amount of material. These are a material's properties such as mass and volume. depend Intensive variables are_________ of the amount of material. WebBy definition, neither heat nor work can be transferred between an isolated system and its surroundings. We can apply the second law of thermodynamics to chemical reactions by noting that the entropy of a system is a state function that is directly proportional to the disorder of the system.
