Entropy of vaporization

Postby Jeffrey Hablewitz 2I » Wed Mar 10, 2021 8:54 pm

How is the entropy of vaporization of a liquid calculated? In Michael's workshop worksheet #6, he states that one can calculate the entropy of vaporization for water at room temp. I was curious how this is computed.

I believe you would divide the enthalpy of vaporization over the temperature in kelvin.

Enthalpy of vaporization at a constant temperature can be found by the following equation: deltaHvap / T(here, 298K)

Is this formula given on the formula sheet? Or are we just expected to memorize it?

The equation deltaS=q/t is given on the equation sheet, so it's basically applying this equation!
