: study of the relationship between various forms of energy (such as work
or heat); study of the transformation of energy.
: Energy book-keeping. Heat absorbed or evolved in a chemical reaction.
Thermodynamic (Equilibrium) State
: The condition of a substance or system, defining its
properties, specified by a few intensive macroscopic variables (such as T, P, etc.).
: a physical property like U, H, T, V, P that has a specific value once the state is
defined; it depends only on the state of the system and not the pathway (how we got there).
Extensive Macroscopic Variables
: properties that depend upon the amount (mass) or “extent”
of the sample
, properties like mass M, mole numbers n
, volume V, heat capacity C, internal
energy U, entropy S, Gibb’s free energy G, etc.
Intensive Macroscopic Variables
: properties that depend on the nature of the material
the amount, such as temperature T, pressure P, viscosity η, and any ratio of extensive properties
