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?
Yes
How will adding different different flavors of kool-aid to water affect the waters boiling point?
the Kool-Aid will make the water boil faster
Why does water with oil boil faster than plain water?
because the oil makes the water have more heat which makes the water boil fast.
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.
Why does water boil faster in the mountains than the city?
There is Less atmospheric pressure on a mountain. As pressure goes down, so does the temperature required to boil water.
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 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.
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.
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 evaporate faster with lid or no lid?
Less heat will escape with the lid on. As the pressure inside the pan increases, the liquid boils faster - so both aspects combined makes the water to boil faster and save energy. Without a lid, the water won't boil as fast or as quickly, and more energy will be used.
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.
Does water boil faster with or without sugar?
With sugar. Increased density increases its absorbsion pf heat.
What would a diagram look like for the question Does salt water boil faster than plain water?
yes salt water does boil faster
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.
