Interpretation:
The normal boiling point and vapor pressure of Ethanol has to be estimated.
Concept Introduction:
Entropy of Fusion:
At the temperature, where there change in phase occurs, the two phases co-exist in equilibrium and
Rearranging the above equation,
Equilibrium vapor pressure:
The pressure throw by vapor of the substance is equilibrium liquid or solid state of same substance is called the equilibrium vapor pressure, thus,
The liquid is boiled when the vapor pressure of liquid is equal to atmospheric pressure.
