From the Wikipedia article (linked to the left of this answer): "Trouton’s rule states that the entropy of vaporization is almost the same value, about 87-88 J K-1 mol-1, for various kinds of liquids. The entropy of vaporization is defined as the ratio between the enthalpy of vaporization and the boiling temperature." This value of 87-88 J K-1 mol-1, Trouton's constant, is also about equal to 10.5 * R, where R is the universal gas constant (R = 8.314472 J K-1 mol-1).
Trouton's constant is a physical property that characterizes the relative volatility of a liquid. It is calculated as the ratio of the heat of vaporization to the boiling point of the liquid at its normal boiling point. Trouton's constant is approximately 21 J/mol·K for most organic liquids.

If the mass of an object does not change a constant net force on the object produces a constant what?
If the mass of an object does not change, a constant net force applied to the object will produce a constant acceleration according to Newton's Second Law (F=ma). This means that the object will continue to accelerate at a constant rate as long as the force is applied.
What is a substance with constant consumption?

Is universal gas constant equal Avogadro constant?
of course. that's why it's called the universal gas constant.
Are global winds constant?

What is the SI unit of radiation constant?
In the SI system the radiation constant (Stefan-Boltzmann constant) is measured in W/m2.K4.
What is the troutons constant for chloroform?
The Trouton's constant for chloroform is approximately 90 J/mol*K. It is a measure of the entropy of vaporization of a substance.
What is the constant equal to the ratio of the gas constant to the avogadro constant?
Boltzmanns constant
What is 2.71828182845904?
It is the e mathematical constant, Euler's constant.
Is the spring constant is constant on the moon?
no the spring constant is not constant on moon because there is no restoring force there
How do you find constant in math?
The answer depends on what the constant is: the y-intercept in a linear graph, constant of proportionality, constant of integration, physical [universal] constant.
What are different NAME of constant r?
Some common names for the gas constant, ( R ), include ideal gas constant, universal gas constant, and molar gas constant.
What is a monomial that is a real number with no variable?
A [real] constant.
What is a medial consonant?
constonant vowel constant constant vowel constant
Does the gas constant R vary with temperature?
No, the gas constant, or any constant, is constant meaning it doesn't change.
What are length constant and wedge constant in newton's laws of motion?
"What are length constant and wedge constant in newton's laws of motion?"
What is Boltzman's constant?
The Boltzman's constant is the physical constant relating to temperature to energy.
What is the difference between a constant in a graph and a constant in a experiment?
the difference between a constant in a graph and a constant in a experiment is that when on a graph, the constant is the thing that changes, and in a experiment it is the part that stays the same.
