The calculator below can be used to calculate the water boiling point at given absolute pressures. The boiling point of water can change significantly based on altitude and the difference between local air pressure and the standard day. It takes more kinetic energy, or a higher temperature, to break the hydrogen bonding between water molecules, thus allowing them to escape as steam. The larger the number of salt molecules added to a given volume of water, the greater the degree of boiling point elevation. or atom; t - temperature, °C. Boiling Points for Water and Ethanol at Different Altitudes & Atmospheric Pressures. The difference in the boiling point between typical supplies of hard and soft water is about a degree or two. Your pot of water will come to a boil sooner as it will boil at a lower temperature than at sea level. The boiling point of water also depends on the purity of the water. You can also contrast the boiling point of water to the boiling point of milk. It should be noted that the only actual factor that is truly involved in the variance of boiling water is the pressure.
