This formula uses 5 Variables

Variables Used

Surface Enthalpy - (Measured in Joule per Kelvin) - Surface Enthalpy is the measure for energy i.e. the heat content of a surface.
Constant for each Liquid - Constant for each Liquid is the constant being the surface tension of a liquid at absolute zero.
Temperature - (Measured in Kelvin) - Temperature is the degree or intensity of heat present in a substance or object.
Critical Temperature - (Measured in Kelvin) - Critical Temperature is the highest temperature at which the substance can exist as a liquid. At this phase boundaries vanish, and the substance can exist both as a liquid and vapor.
Empirical Factor - Empirical Factor is the value originating in or based on the empirical observation that relates the surface tension to the critical temperature.

STEP 1: Convert Input(s) to Base Unit

Constant for each Liquid: 55 --> No Conversion Required
Temperature: 55.98 Kelvin --> 55.98 Kelvin No Conversion Required
Critical Temperature: 190.55 Kelvin --> 190.55 Kelvin No Conversion Required
Empirical Factor: 1.23 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H_s = (k_o)*(1-(T/T_c))^(k₁-1)*(1+((k₁-1)*(T/T_c))) --> (55)*(1-(55.98/190.55))^(1.23-1)*(1+((1.23-1)*(55.98/190.55)))

Evaluating ... ...

Why is heat absorbed on expansion of a surface?

The reason heat is absorbed on the expansion of a surface is that the molecules must be transferred from the interior against the inward attractive force to form the new surface. In this process, the motion of the molecules is retarded by this inward attraction, so that the temperature of the surface layers is lower than that of the interior unless heat is supplied from the outside. The same is true when a gas molecule adsorbs on a solid surface.
