Question

How can we calculate the heat of vaporization of any gas if we know the

temperature and pressure of the given gas at two different states?
​

Answer 1

Explanation:

Use the formula q = m·ΔHv in which q = heat energy, m = mass, and ΔHv = heat of vaporization.

simple_pressure = e^(20.386 - (5132 / (temperature + 273)) , where vapor pressure is expressed in mmHg and temperature in kelvins.
