Continuum Thermodynamics

Continuum thermodynamics substitutes a few average quantities like temperature \bgroup\color{blue}$ T$\egroup, pressure \bgroup\color{blue}$ P$\egroup, and internal energy \bgroup\color{blue}$ U$\egroup that represent the state of a system. These averages reduce the enormous number of variables that one needs to start a discussion of statistical thermodynamics: the positions and momenta of zillions of particles.
