Thermodynamics

Thermodynamics Skill

Trigger Patterns

• "calculate enthalpy"
• "find vapor pressure"
• "thermodynamic properties"
• "heat capacity"
• "Clausius-Clapeyron"
• "phase diagram"

Steps

1. Identify the substance — Use CoolProp's fluid database (180+ fluids)
2. Determine the state — Temperature, pressure, or quality (vapor fraction)
3. Look up properties — Use CoolProp: PropsSI('H', 'T', T, 'P', P, fluid)
4. Apply equations — First/second law, energy balances, entropy calculations
5. Unit conversion — Use Pint for all unit conversions (never manual)
6. Validate — Cross-check with NIST WebBook data
