Question

When ice melts to become water,which force must be overcome? A)the attraction between electrons and the nucleus. B)the attraction between the atoms in a molecule C)the force between molecules. D)the force of gravity​

Answer 1

C) The force between molecules

Answer 2

The ice melts to become water in the force between molecules.

Explanation:

• Ice is less dense or lighter than water because of its porous or cage like structure on account of the presence of intermolecular hydrogen bonding in $H_{2}O$ molecules.
• When ice is melted to form water, energy has to be supplied.
• To overcome attractive forces on account of hydrogen bonding.
