Does salt make water boil faster?

Answer 1

NO

As soon as any of the salt dissolves in the water, the boiling point of
the water
will begin to rise -- by about one half degree Celsius for every 58 grams
of salt
dissolved per kilogram of water. In fact, any non-volatile soluble
substance will
raise the boiling point of water. That is why antifreeze (ethylene glycol)
provides boiling protection in winter as it simultaneously provides freezing
protection in the summer.

Referring to the specific situation you described: I will assume that the rather
small amount of salt added (relative to the much larger volume of water)will be
completely dissolved well before ebulliation commences. If so, the salted water
will require more exposure to the heat before boiling than would the distilled
water. So the salted water "boils slower" than the distilled water. Nevertheless,
under these real-world conditions of low salt concentration, it would be
difficult to tell which pot boiled first.

Answer 2

Yes and no. If you look at how fast water boils when you add a small amount of salt to it, such as when cooking your noodles, the change is insignificant between pure water and the salted water. However, if you take two identical pots and add one gallon of pure water to one pot and one gallon of 20 percent salt water to the other and heat the two pots on identical stoves, the pot containing the salt water will come to a boil first.
It takes less energy to raise the temperature of the salt water 1°C than pure water. This means that the salt water heats up faster and eventually gets to its boiling point first.

Answer 3

June L is right, salt does make water boil faster...

Answer 4

adding salt to water raises the boiling point, so you will have to add more heat to get it to boil, and that would take longer.

Answer 5

yes

Answer 6

yes

Answer 7

No. But it helps the cooking of macaroni.

Answer 8

Actually it makes if boing slower.

Answer 9

YES

Answer 10

yes! ive tried it!
