Richmann's law, [1] [2] sometimes referred to as Richmann's rule, [3] Richmann's mixing rule, [4] Richmann's rule of mixture [5] or Richmann's law of mixture, [6] is a physical law for calculating the mixing temperature when pooling multiple bodies. [5]
The temperature used in the equation of state is an ... and temperature in a unique formula independent of the quantity of the considered gas. ... In the final three ...
The temperature approaches a linear function because that is the stable solution of the equation: wherever temperature has a nonzero second spatial derivative, the time derivative is nonzero as well. The heat equation implies that peaks ( local maxima ) of u {\displaystyle u} will be gradually eroded down, while depressions ( local minima ...
That is a final temperature of 753 K, or 479 °C, or 896 °F, well above the ignition point of many fuels. ... By the continuous formula, = () ...

Temperature is a physical ... which states that physical quantities must assume every intermediate value between a starting value and a final ... gives a formula for ...
Integrating both sides yields =, where c v is the specific heat capacity at constant volume, T 1 is the initial temperature and T 2 is the final temperature. We conclude with: Δ Q = m c v Δ T {\displaystyle \Delta Q\ =mc_{\mathrm {v} }\Delta T}
(Note - the relation between pressure, volume, temperature, and particle number which is commonly called "the equation of state" is just one of many possible equations of state.) If we know all k+2 of the above equations of state, we may reconstitute the fundamental equation and recover all thermodynamic properties of the system.
