salt has to break down first
yes salt water does boil faster
Salt changes the molecular composition of the water, causing its boiling point to go up. That's why it takes it longer to boil.
For salt water to boil faster than plain water, the salt concentration would have to be fairly high. In addition, the salt water would need to be a salt water solution before putting the pot on to heat because of the density of the water content itself.
salt water pot heat source thats all you need
yes! it does when you add the salt to the boiling water it goes up by two degrees. and that makes the water boil more and cooks the spaghetti faster.
A liquid boils when the vapor pressure of the liquid is equal to the atmospheric pressure. The presence of salt in the water reduces the vapor pressure of the water at the temperature at which plain or distilled water will boil. Since the temperature of the salt water must be higher to reach the same vapor pressure as the atmosphere, it takes longer to boil.

Salt (or anything dissolved into water) will increase the boiling point of water. It will take longer to come to a boil. Salt reduces the vapor pressure of the water and so requires a higher energy level to boil.
Raises the temperature at which the water boilsAdding salt does not make the water boil faster, but makes the water boil at a higher temperature than 100 degrees Celsius. This may allow you to cook food in that water faster than in plain boiling water.
Plain water evaporate faster.

salt helps to bring the water to the boil faster.
