Does adding salt to the water make a meal boil faster?

Answer 1

Adding salt to water doesn't take any longer to boil meal than unsalted water. In real sense there will be a very little increase in time to boil yet such increase is so little considered as negligible.
When salt is dissolved in water, the boiling point of the water does increase and therefore requires more energy (or time) to boil. However, in order to appreciably increase the amount of time it takes to boil a pot of water, you would have to add a lot more salt than you would normally add in cooking.According to Professor Wolke, a tablespoon of salt in five quarts of water will raise its boiling point by seven hundredths of a degree Fahrenheit (about 4 hundredths of a degree Celsius). thus the additional half second or so this adds to the clock is negligible.

Salt, water, and boiling points

Question: When salt is added to water will the salt make the water boil faster?

Answer 1: Just the opposite: salty water boils at a HIGHER temperature, so you
might say that it boils slower. Salt water also freezes at a lower temperature
than pure water.

Answer 2: No, just the opposite. Salt water boils at a higher temperature than
fresh water. -ProfBill

Answer 3

No, it makes the food cook faster.....

By dissolving salt in water, both the freezing point and boiling point of water are affected. By doing this experiment, we can see that the boiling point of water (normally 100 degreees Celsius or 212 degrees Fahrenheit) increased as a result of the addition of salt or any other solute. Similarly, the addition of a solute also lowers the freezing point of water. This is why we spread salt over ice to make it melt in the winter.
You're forgetting that the boiling temperature is as hot as it's going to get (cuz after that temp, the extra heat is pretty much going to be released in vapors off the water) -- by raising the boiling temp, you're allowing the food to cook at a higher temp, thus get done faster.

Answer 4

Not according to the "Interesting Thing of the Day" web site. Chemically speaking, salt raises the boiling point of water, so it would actually take longer to boil. The small amount that's usually added to water for cooking makes a negligible difference, though.

Answer 5

Adding salt raises the boiling temperature, so the water is hotter, so the food cooks faster.

Answer 6

No, actually, it slows down the boiling process. But the good news is, it raises the boiling temperature. So instead of boiling at 212ºF, it boils a little hotter. Which will cookyour pasta faster.

Answer 7

It should take longer. Adding salt to the water changes its density. Fresh water floats on top of salt water because it is less dense.

Higher density equals a higher boiling point, but I honestly can't imagine this making much difference on the stovetop. The density difference is something like 1.0:1.025.

Answer 8

The water will boil faster. I'm not sure about "the meal".

Answer 9

the water boils faster when I use salt but I'm not for sure.

Answer 10

Yes salt does make it boil faster, if you put a lid on the pot and have your burner turned to high
