What are the relationships between melting and freezing of a mixture

What is the source of continuous heat and energy that we receive from the sun

An uncovered pot of water lies out in the sun. which statements correctly describe what happens at the surface of the liquid water? 1. the vapor pressure remains constant regardless of the water temperature. 2. the vapor pressure is produced by water molecules that have evaporated. 3. the vapor pressure increases as the sun heats the water in the pot. 4. evaporation stops once the vapor pressure reaches a certain point. 5. evaporation and condensation both occur on the liquid’s surface.

How does the kinetic energy of a substance's particle in the solid phase compare to their kinetic enegy in the liquid phase?
