Water boiling at 99.3 °C (210.8 °F) at 215 m (705 ft) elevation. The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid [1] [2] and the liquid changes into a vapor. The boiling point of a liquid varies depending upon the surrounding environmental pressure.
At 20 °C (68 °F) one liter of water can dissolve about 357 grams of salt, a concentration of 26.3 percent by weight (% w/w). At 100 °C (212 °F) (the boiling temperature of pure water), the amount of salt that can be dissolved in one liter of water increases to about 391 grams, a concentration of 28.1% w/w.
The salt water will boil ever so slightly slower, and hotter. As an aside, any food in the pot will cook faster in boiling water at 100°C than it will in not-yet-boiling-salt-water at 100°C. This is because steam at 100°C has much more internal energy than water and can transfer it to the food faster through the agitation of a rolling boil.

Cold water does not boil faster. Water boils when it reaches its boiling point of 212 degrees Fahrenheit, 100 degrees Celsius or 373 degrees Kelvin.
Boiling-point elevation is the phenomenon whereby the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water.
Rolling boil of water in an electric kettle. Boiling or ebullition is the rapid phase transition from liquid to gas or vapour; the reverse of boiling is condensation.Boiling occurs when a liquid is heated to its boiling point, so that the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.
The salt from this slab is mined using large rigs, which take away millions of tonnes every single day. What’s more, while this might be the country’s largest salt mining operation, it does ...
