In most liquids,with a rise in temperature,the surface tension of a liquid

The property utilized in the manufacture of lead shots is

Assertion $(A)$: At critical temperature,the surface tension of liquids becomes zero.
Reason $(R)$: At critical temperature,the intermolecular forces for liquids and gases become equal.

What tendency do molecules on the surface of a liquid possess?

If the surface area of the soap solution is increased,then its surface tension

With an increase in temperature,surface tension of liquid (except molten copper and cadmium)
