From the Clausius Clapeyron equation, d P d T i → j = ℓ i → j T ( v j − v i) Where ℓ i → j is the latent heat of going from phase i to phase j, v is the specific volume, and all other variables have their common meaning. Taking for example water, this equation gives the change in temperature as the pressure ...
