Question

(d) What is parachor? Find an expression
for it.​

Answer 1

Answer:

Parachor is a quantity defined according to the formula: P = γ1/4 M / d. where γ1/4 is the fourth root of surface tension, M is the molar mass, and d is the density. Parachor has a volume multiplier and is therefore extensible from components to mixtures. Parachor "has been used in solving various structural problems".

Answer 2

Explanation:

Parachor:- It is defined as the molecular volume of liquid when its surface tension is unit. Macleod (1923) gives relation between surface tension and density of liquid as γ = surface tension C = Macleod constant --- (1) D = density of liquid.

parachor and its appication.

an empirical constant for a liquid that relates the surface tension to the molecular volume and that may be used for a comparison of molecular volumes under conditions such that the liquids have the same surface tension and for determinations of partial structure of compounds by adding values obtained for constituent ...
