Interpretation:
The normal boiling point of
Concept introduction:
The vaporization curves of major liquids have same shapes. The vapor pressure consistently increments as the temperature increments. A better method is to discover the mathematical approach for the increment in pressure as a function of temperature. experiments appeared that the temperature T and vapor pressure P are connected,
Here,
R = constant
So, if we assume that, P1 as well as P2are the vapor pressures at two temperatures T1 and T2, then we can find a below simple connection
This is recognized as the Clausius-Clapeyron Equation and permits us to assess the vapor pressure at a different temperature, if the vapor pressure is identified at certain temperature, and if an enthalpy of vaporization is identified.
