Question

How do intermolecular forces affect the state of a compound/substance?

Answer 1

Intermolecular forces have a great affect on the state of a substance or it would not be wrong if i say it os the only propertt by which state of a compound is affected...

If the intermolecular spaces are very less , it means that the intermolecular force of atraction is very high and the substance is a solid, if the intermolecular spaces are somewhat more than the solids but less then gases then the state of substance is liquid, and if the intermolecular spaces are very large then the state of substance is gas...

I am not considering plasma and BEC here becoz they are not in syllabus for elementaty science.

$\huge\text{Answer}$

● If the $\bold{intermolecular\:forces}$ are $\bold{strong}$ , the $\bold{molecules}$ $\bold{don't\:move}$ apart, hence the substances are $\bold{solids}$

● If the $\bold{intermolecular\:forces}$ are $\bold{moderately\:strong}$, the molecules $\bold{flow}$, $\bold{slide}$ over each other, hence the substances are $\bold{liquid}$

●if the $\bold{intermolecular\:forces}$ are $\bold{weak}$, the molecules move $\bold{easily}$, hence they are $\bold{gases}$
