In physics, chemistry, and thermodynamics, an equation of state is a thermodynamic equation relating state variables, which describe the state of matter under a given set of physical conditions, such as pressure, volume, temperature, or internal energy. Most modern equations of state are formulated in the Helmholtz free energy. Equations of state are useful in describing the pr… WebThe ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas.It is a good approximation of the behavior of many gases under …
