Vedclass · Answer

(D) Statement $A$ is incorrect because surface tension arises from unbalanced attractive forces on the surface,not equal forces in the bulk.Statement $B$ is correct because molecules on the surface experience a net inward pull,leading to surface tension.Statement $C$ is incorrect because molecules in the bulk are in constant motion and can reach the surface due to their kinetic energy.Statement $D$ is correct because molecules on the surface have higher energy and can escape into the gas phase,creating vapour pressure in a closed system.Therefore,there are $2$ correct statements ($B$ and $D$).
