Rising of liquid is due to adhesion between the water molecules and glass.
Depression of liquid (eg mercury when glass tube is dipped) due to high cohesive force between the mercury molecules.

The capillary action is due to the pressure of cohesion and adhesion which cause the liquid to work against gravity.

Answer correct because of its liquid pressure increased so change its viscosity temperature and contractions.

The height liquid rises in the glass tube is depend upon the density of the fluid as per the formula.

It is rise due to the cohesion and adhesion property of capillary phenomenon of surface tension.

It is rise because of the atmospheric temperature lower than that of the internal pressure.

Wetting of surface because of viscosity whereas rise in water because of surface tension.

If d>5mm due to capillarity, Capillarity rise in water & capillarity dip in mercury.
