Q. 28

# Consider an ice cube of edge 1.0 cm kept in a gravity-free hail. Find the surface

area of the water when the ice melts Neglect the difference in densities of ice and water.

Answer :

(36 π)^{1/3} cm^{2}

Given, volume is

As the densities are to be neglected, we assume that the volumes do not change when state changes.

As gravity has no effect here, the water after melting will form a sphere(least surface area) of radius .

Hence,

The surface area of the sphere will then be
