In mechanics, the virial theorem provides a general equation that relates the average over time of the total kinetic energy of a stable system of discrete particles, bound by potential forces (forces characterized exclusively by potential difference), with that of the total potential energy of the system. Mathematically, the theorem states The significance of the virial theorem is that it allows the average total kinetic energy to be calcu… WebWe will consider the ideal, van der Waals, and virial equations of state, as well as others. The use of equations of state to predict liquid-vapor diagrams for real gases will be discussed, as will the commonality of real gas behaviors when … Webempirical equations of state have been constructed to describe the deviations from the simple ideal gas law. The most fundamental of these, in the sense that it has the soundest theoretical foundation, is the so-called virial equation of state.
