Web13 mei 2024 · We can use the equation of state to derive the relation between the volume change and the pressure change. The equation of state is: p * v = R * T where v is the specific volume occupied by the gas. If we substitute this expression for T into the temperature equation, we obtain: (p2 * v2) / (p1 * v1) = (p2 / p1) ^ [ (gamma - 1)/gamma] WebGibbs free energy and spontaneity. When a process occurs at constant temperature \text T T and pressure \text P P, we can rearrange the second law of thermodynamics and define a new quantity known as Gibbs free energy: \text {Gibbs free energy}=\text G =\text H - \text {TS} Gibbs free energy = G = H − TS. the nanny company winnipegWebExample 6.4.
