Kirchhoff's equation: Difference between revisions

Latest revision as of 13:05, 26 March 2024

A relation that equates the variation with temperature of the latent heat of a phase change to the difference between the specific heats of the two phases.

For the heat of vaporization this may be written as

where L_v is the latent heat of vaporization, c_pv is the specific heat at constant pressure of water vapor, and c_w is the specific heat of liquid water.
