Question

Parachor [P] value of a substance is determined by​

Answer 1

Answer:

Drop Number method

it is used to determine parachor , additive and constitutive property used to investigate molecular structures of compounds.

Answer 2

Answer:

It is defined according to its formula, where is the surface tension, is the molar mass, is the liquid density, and is the vapor density in equilibrium with the liquid. Because Parachor has a volume multiplier, it can be used in a wide range of applications, from components to mixtures.

Explanation:

The difference between the density of the liquid and the density of the vapor in equilibrium with it is divided by the molecular weight of the liquid times the fourth root of its surface tension; essentially constant over wide temperature ranges.

The Parachor is defined by the following relationship:

Pc=My$1$/$4$/(pl-lg), where is the liquid's surface tension and pI and pg are the liquid's and vapors' densities in equilibrium at the given temperature. P = y1/4 M / d, where is the surface tension, M is the molar mass, and d is the density, is a quantity (related to surface tension) defined by the formula: P = y$1$/$4$ M / d.

The difference between the density of the liquid and the density of the vapor in equilibrium with it is divided by the molecular weight of the liquid times the fourth root of its surface tension; essentially constant over wide temperature ranges. It is a molecule's additive constitutive property that is related to the molar volume and the molecular weight.
