Web46 languages. 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. [1] Most modern equations of state are formulated in the Helmholtz free energy. WebElliott and Lira : Chapter 5 – Classical Thermodynamics Slide 2 Example. Enthalpy of H2O above its saturation pressure
WebFeb 2, 2011 · A perfect gas is a gas, which follows the equation of state: where p denotes the pressure (N/m 2 ); the molar volume (m 3 /mole); (= 8314 J/mole K or 8314 kJ/kmole K) the universal gas constant; and T absolute temperature, K. If both sides of the equation are divided by (the molecular mass of a given gas), the equation will be: WebSep 24, 2016 · This holds true for a perfect gas, and one can quickly obtain the desired relation at this stage.
