Nature of thermodynamic functions
The properties of a thermodynamic system depend
on variables which are measurable and change in values when the state of the
system changes. These variables are classified as state variables or state
functions and path variables (or) path functions.
The state
functions considered in a gaseous system like, P, V and T are called as
state variables. A state function is
a thermodynamic property of a system which has a specific value for each state
of the system and does not depend on the path (or manner) in which a particular
state is reached. Other than P,V,T there are other important thermodynamic
properties existing as state functions like internal energy (U), enthalpy (H),
free energy (G) etc. (The properties of U,H and G are to be studied later).
