... A thermodynamic system is in thermodynamic equilibrium when all its state variables remain constant with time: there is no net flow of matter or energy, no phase changes, and no unbalanced potentials (or driving forces) within the system. A system that is in thermodynamic equilibrium experiences no ...

Introduction to Physical Chemistry
... The pressure (P) of a gas depends on its temperature (T) and volume (V), so P=f(T,V). Write the general differential for P. dP = Assuming that the gas is ideal (that is, there are not intermolecular forces and the individual gas particles occupy no volume), the ideal gas law (PV=nRT) can be used to ...
