Gibbs-thomson coefficient

WebJun 13, 2024 · At any given pressure and temperature, the Joule-Thomson coefficient, μJT, is the slope of this curve. We can also express μJT as a function of the heat capacity, CP, and the coefficient of thermal expansion, α, where α = V − 1(∂V / ∂T)P. We begin by expressing d¯ H as a function of temperature and pressure: d¯ H = (∂¯ H ∂T)PdT ...
