•Freezing point= melting point: 0°C (32°F) •Boiling point = condensation point: 100°C (212°F) • Freezing and boiling points of water unusually high Temperature - Freezing and Boiling Points
The higher the concentration of ions (or molecules) in solution the higher is the boiling point of the solution For seawater with a salinity of 35 the boiling point is higher by about 0 3 deg C 3 Freezing point depression 4 Seawater freezes at a temperature about 2 deg C lower than freshwater Air-Sea Equilibrium
Normal Water is sea water whose chlorinity has been adjusted to about 19 4 */00and accurately determined by either direct or indirect comparisons with the original standard prepared in 1902 Hence the chlorinitiesof allbatches have been independent of changesin the atomic weights

Does water have a high boiling point?
Water has a high boiling point because its molecules are bound together by hydrogen bonding, which is a very strong intermolecular force. It takes more kinetic energy, or a higher temperature, to break the hydrogen bonding between water molecules, thus allowing them to escape as steam.
How to increase boiling point of water?
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!
Can you raise the boiling point of water?
You can increase boiling points of any liquid by applying,i e putting it in a pressure cooker. When you place some food in a pressure cooker it is cooked by the water without causing the water to boil. Even though the heat is sufficient to boil the water at atmospheric pressure.
