Solution
The correct options are
C Remains same
D Vapour pressure is not dependent on surface area.
Vapour pressure is the pressure exerted by a vapour on its liquid (or solid) at equilibrium in a closed container.
Vapour pressure does not depend on the surface area of the liquid because vapours produced from the surface increases on increasing the surface area. Hence the ratio of numbers of vapours produced to surface remain the same.
It is given in the question that the surface area of the liquid is increased. Since vapour pressure is not dependent on surface area, it remans the same. Therefore c and d are correct options.
