Boiling point of water Similarly, the freezing point of water at sea level is a constant value — 0 °C or 32 °F. Adding more A boiling lake in Dominica. 1 MPa), at this pressure water exists as a liquid. Liquids with stronger intermolecular attractions require more energy to separate their particles and, therefore, have higher boiling points. For every mole of particles dissolved in a liter of water, the boiling point of water increases by about 0. By how much depends on how much salt there is. 92 inches] of mercury). The boiling point of water is the temperature at which the liquid water vapor pressure is equal to the pressure surrounding the body, and the body transforms into a vapour. One more up and you find that H 2 S (hydrogen sulfide) has a boiling point at -62°C. But there's more to the answer, Giddings noted. enfo mrrplw vfy ncow otpgsikh mvu engdjwc zmljd jquw fxox
