What happens when salty water is boiled?
The salt becomes a new compound and water evaporates as it has a low boiling point
The water evaporates and the salt remains in the beaker as it has a high melting point
The water becomes a new compound and evaporates while salt remains in the beaker
The water will disappear and the salt remains in the beaker as it is a solid
