What is Duhem’s Theorem?
For any closed system formed from known amounts of prescribed chemical species, the equilibrium state is completely determined when any two independent variables are fixed. The two independent variables subject to specification may in general be either intensive or extensive. However, the number of independent intensive variables is given by the phase rule. Thus when F = 1, at least one of the two variables must be extensive, and when F = 0, both must be extensive.
How to Calculate Enthalpy using Internal Energy, Pressure and Volume?
Enthalpy using Internal Energy, Pressure and Volume calculator uses Enthalpy = Internal Energy+Pressure*Volume to calculate the Enthalpy, The Enthalpy using Internal Energy, Pressure and Volume formula is defined as the sum of internal energy and the product of pressure and volume. Enthalpy is denoted by H symbol.
