Question

What is the parachor value of methanol?

Answer 1

The parachor value is 240.61+0.26 as against a calculated value (from atomic parachors) of 240.10 for methanol, the average value of the temperature coefficient of density ,ddldt is 0.00094 per deg,between 25" and 50".

Answer 2

Parachor value of methanol at 20 oC is 88,11.

Explanation:

• Parachor value is the  constant that states the relation between the surface tension and the  molecular volume

• It can be used for a comparing the molecular volumes.

• This value was first found by Sugden  in 1924.

• Parachor  value can be found by $\bold{P = \gamma ^{\frac{1}{4}} M / d}$ where the gamma represents the surface tension, M is the molar mass and d is the density.

• The parachor has been used to determine the structure of a number of substances.
