The equation used is q = m⋅ ΔH, where ΔH - the heat required for one gram of the substance to undergo the phase change. If you're going from solid to liquid, you use ΔH fusion (called the heat of fusion ), which represents the heat required for 1 gram of substance to change from solid to liquid at melting point. Clapeyron Equation - Teaching Phase Equilibria The Clapeyron equation (also called the Clausius-Clapeyron equation) relates the slope of a reaction line on a phase diagram to fundamental thermodynamic properties. What is the Clapeyron Equation? The reaction brucite = periclase + H2O. This reaction has a typical shape for a dehydration (or decarbonation reaction). Figure from D. Perkins.

Differential Equations - Phase Plane - Lamar University In this section we will give a brief introduction to the phase plane and phase portraits. We define the equilibrium solution/point for a homogeneous system of differential equations and how phase portraits can be used to determine the stability of the equilibrium solution. We also show the formal method of how phase portraits are constructed.
