ThermoPhase

ThermoPhase is a thermodynamics calculation tool based on the Clapeyron equation.

Features:
General Clapeyron Calculator: Input enthalpy of transition, volume change, temperature, and pressure change to calculate new phase transition conditions
Water Vaporization Preset: Pre-configured with water boiling parameters (ΔH = 40.7 kJ/mol) for quick boiling point estimation under different pressures
Ice Melting Preset: Pre-configured with ice melting parameters (ΔH = 6.0 kJ/mol) for melting point calculation under pressure
Formula Reference: Complete documentation of the Clapeyron equation, derivation notes, unit conversions, and common phase transition examples
The Clapeyron equation (dP/dT = ΔH / (T × ΔV)) is a fundamental relation in thermodynamics that describes the slope of phase boundary curves. This app uses a linear approximation to estimate temperature shifts under pressure changes.
