Question

Two molecules of a solid are kept some distance apart and the force between them is measured. The solid is then melted to form a liquid. Two molecules of the liquid are now kept the same distance apart and the force between them is measured. Which force will be greater? Explain why.

Answer 1

The force between the various states of matter depends upon the distance between the particles. Here, the nature of the molecule in both the phases i.e solid and liquid is same as well as the distance between the particles in both the cases is same, so force will remain the same in both cases.
