My science teacher might be able to answer that

Any bits of grit help boiling water start boiling. People use salt cuz it will be in the food at some point anyway. Without the small particles, the churning water doesn't start. (Catalitic reaction?)
When microwaves got popular, folks noticed that nuking a cup of water was dangerous. You put in the spoon and the water leaps up & burns you. They realized that a very clean cup, without the small particles to help the water begin to churn the water, only allowed the water to heat. The spoon had enough stuff on it to help the water start boiling, and thats how the water lept up.

Salt molecules create a lot strogner bond, called ionic bond, among water molecules. This makes it harder for the water molecules to escape from the bond into the atmosphere through the surface as evaporation. Thus, it requires more energy, in the form of heat, for the water to boil.

Salt water needs to be higher than 212 degrees to boil.

Soluble molecules develop the boiling factor, and shrink the freezing factor. The style of species contemporary, impacts the degree,and the elevation consistent, i think of for water it extremely is 5.2 tiers C there is not any provide up start up mechanism, it purely boils at a miles better temperature.

Because water is a polar molecule, the ionic compound Sodium chloride (table salt) dissolves in it. The positively charged sodium ions are surrounded by 6 water molecules, with the oxygen atom(slightly negative) in the water molecule directed inwards towards the positive ion. The Chloride ion is surrounded by 6 molecules of water, this time with the negative ion attracting the "hydrogen side" of water molecules (see link for diagram).
A larger amount of energy is required to seperate water molecules attracted to a dissolved ions compared with free water molecules. Whilst only a fraction of water molecules are bound to an ion, this is enough to affect the temperature required to evaporate the water (by 1c)

The more salty the water, the higher the boiling point.

salt raises the BP of water. so the temp is higher when it starts boiling

Listen very close as i will NOT repeat myself.....
The above chemists ARE WRONG.!!! Salt water boils at a LOWER temp..
