13 Ιουλ 2024 · If you add salt to water, you raise the boiling point, or the temperature at which water boils. The temperature needed to boil will increase by about 0.5 C for every 58 grams of dissolved salt per kilogram of water.

- Boiling Point Elevation
The boiling point is raised by 0.5 degrees Celsius for water with 29.2 grams of salt dissolved in each kg of water. If your concentrations of salt are different, then you can scale the boiling point elevation and melting point depression predictions directly with the concentration.
22 Σεπ 2016 · According to an old wives' tale, adding salt to a pot of water on the stove will make it boil faster. The tale is true, but the difference is negligible, an expert told Live Science.
16 Μαΐ 2023 · The boiling point of water increases when salt is dissolved in it. This phenomenon is known as boiling point elevation. When a solute, such as salt (sodium chloride, NaCl), is added to a solvent, such as water (H2O), it disrupts the normal boiling process.
Salt (or other solutes, like sugar) can easily dissolve in liquid water. However, taking the solute out of the water and putting it in the gas phase (air) requires a lot of energy. At temperatures around the water boiling point, these solutes stay in the liquid.
6 Αυγ 2020 · The normal boiling point of water is 100 °C, 212 °F, or 373.1 K. The “normal” refers to sea level or an elevation of 0 meters or feet. But, the boiling point of water changes with elevation. The boiling point is a higher temperature below sea level and a lower temperature above sea level.
This resource explores why salt is always added to the water when cooking.
