Anybody whose taken chemistry would know that adding salt to water raises the boiling point of water so it takes longer for the water to reach the boiling point, but it'll be at a higher temperature so whatever you're boiling wont take as long. Adding more salt wont raise it higher than its already going to be though. Maybe you should all go back to high school and learn something.

Hmm... Adding salt to the water RAISES the boiling point. Your stuff cooks faster because it is actually boiling at HIGHER temperature. It doesn't make it boil faster, it just makes things cook faster.. by the way, water does NOT have the highest specific heat of anything. Really specific heat has nothing to do with it, it is all about boiling point elevation.

Actually salt increases the temperature at which water boils. It is a principle called boiling point elevation. When you add a solute (salt) to a solution (water) it increases the temperature at which the solution boils. However, it takes a LOT of salt to alter the boiling point appreciably. If you are adding a Tbsp of salt to increase the boiling point you're not going to get too far. It only increases the temp tenths of a degree. The opposite of this principle is freezing point depression - this is why we salt roads during the winter; salt lowers the temperature at which water freezes.

actually salt increases the boiling temp so it actually takes longer add the salt after it boils

adding salt makes eggs boil faster because it allows the water to heat up to higher temperature, because it changes the specific heat capacity of the solution. The hotter the water, the faster the eggs boil.
