Adding salt to water increases the boiling temperature, causing the water to come to a boil more slowly. This increase in the cooking temperature will, in theory, cause foods boiled in salt water to cook faster. Pure solutions will generally have lower boiling points than mixtures. Adding sugar to the water will have a similar effect but would not be nearly as nice to cook food in!
Note that if pure water is heated up to a high temperature prior to the addition of the salt, the addition could cause the entire pot to start boiling suddenly. This is a result of the grains of salt acting as nucleation sites. This has the effect of making nearly-boiling water actually boil more quickly when salt is added. The tiny amount of salt required to cause a nucleation effect would have no effect on the temperature of the boiling water. In this regard, you can think of the salt as a catalyst, facilitating the change of state of the water from liquid to boiling.
We said "in theory" above because adding salt to water to raise the boiling point for cooking doesn't actually work in practice. The amount of salt you'd typically add to water for cooking would have negligible effect on the boiling temperature. Let's look at some numbers. Assuming fresh water at sea level, you'd need to add 230 grams of table salt to raise the boiling point of one liter of water just 2 degrees C. To raise the boiling point of the two quarts of water you're cooking pasta your pasta in by that same two degrees, you'd have to stir in 435 grams of salt. That's well over half of an entire 737 gram blue Morton salt container! The pasta may cook faster in the hotter water, but people would probably not be coming back for second helpings of your ultra-salty linguini.
Salt added to the cooking water also "hardens" the surface of the starches in pasta, reducing their stickiness. This prevents the pasta from sticking together in clumps. Somewhat counter-intuitively, oil added to boiling water does not reduce the stickiness of the pasta. It does reduce the surface tension of the water, increased by the starches in the pasta. This tends to reduce foaming.
The bottom line is this: You can add a few grains of salt to pure water to kick off the boiling process with nucleation. Beyond that, add salt to water to flavor what you're cooking and to keep the pasta from sticking together. It will not have any measurable effect on cooking temperature or time.

Does salt water boil faster than water with pepper?
No, salt water does not boil faster than water with pepper. Adding salt or pepper to water may change its boiling point slightly, but the difference is not significant enough to affect the time it takes to boil.
Does salt added to water make the water heat up faster than water without salt added and if both are heated to a boil?
NO Normal water boils faster because salt (sodium chloride) breaks up very slowly and since its salt water. The salt binds itself with the molecules of the water therefore increasing the boiling point, hence making it slower to boil. In comparison to normal water, salt water takes longer to boil than normal water.
What would boil faster salt water or unsalted water?
Salt water boils more rapidly then unsalted water.
How much salt do you put in to make the water boil faster?
Adding salt to water actually increases its boiling point, so it will take longer for saltwater to boil compared to plain water. It is not recommended to add salt solely to make the water boil faster.
Does water boil faster at sea level than on the top of a mountain?
Water boils faster at sea level because there is higher atmospheric pressure, which increases the boiling point of water. At higher altitudes, such as on top of a mountain, the lower atmospheric pressure causes water to boil at a lower temperature, which means it takes longer to boil.
Will salt water boil faster than vinegar or sugar?
yes
Why does plain water boil faster than vinegar water?
Adding vinegar to water the effect of boiling point elevation occur.
What boils faster water with vinegar or water with salt?
The liquid that would boil faster between water, water with vinegar, or water with salt would be water. I am sure because i did an experiment and i boiled these three liquids five time and averaged them. Water came out to be that it took the least amount of time to boil.
What boils faster sugar water or vinegar water?
The liquid that would boil faster between water, water with vinegar, or water with salt would be water. I am sure because i did an experiment and i boiled these three liquids five time and averaged them. Water came out to be that it took the least amount of time to boil.
Why does water evaporate faster than vinegar?
Vinegar evaporates quicker then water because the acid inside of vinegar causes the sun to make the molecules inside the vinegar to boil faster then the water so then the molecules inside the vinegar will break apart faster until the vinegar is completely gone Acetic acid enthalpy of vaporization is lower compared to the same property of water.
Does water boil faster with or without water?
With sugar. Increased density increases its absorbsion pf heat.
Does water covered boil faster?
No, water that is covered does not boil faster. Covering the pot can actually trap heat and make the water boil slower.
Will coke or water boil faster?
Coke will boil faster than Gatorade will because Coke has a lower boiling point. This means it will break down faster than Gatorade.
What boils faster salt water sugar water oil water vinger wateror normal water?
Salt water and sugar water boil faster than pure water because the presence of solutes increases the boiling point of water. Vinegar water boils faster than oil water because oil does not mix well with water and slows down the boiling process. Ultimately, normal water would boil fastest, followed by vinegar water, sugar water, salt water, and lastly oil water.
Does water boil faster with or without sugar?
With sugar. Increased density increases its absorbsion pf heat.
Does water boil faster than salt water why?
== ==
Will water boil faster if there is less of it?
A small amount of water will reach it's boiling point sooner than a large amount of water. It will not boil faster.
