How can you increase the boiling point of water?

Boiling points can be changed in several ways. The addition of solutes or other substances usually changes the boiling point. Additionally, changing the pressure on a liquid changes its boiling point. Sugar, salt or other non-volatile solutes in water will usually make the boiling point higher.

Does salt help water boil?

So yes, salt increases the boiling temperature, but not by very much. If you add 20 grams of salt to five litres of water, instead of boiling at 100° C, it’ll boil at 100.04° C. So a big spoon of salt in a pot of water will increase the boiling point by four hundredths of a degree!
