The water molecules that surround the chloride (Cl) orient their charged polar end toward the charged chloride (Cl). By surrounding sodium and chloride, the water molecules prevent the between sodium and chloride from re-forming, which prevents the salt crystal from re-forming.

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
