Question

water can boil more then its boiling point(100.C)​

Answer 1

With that much less pressure, you don't need to apply as much heat to push vapor pressure beyond the surrounding atmospheric pressure – in other words, water boils at a lower temperature. Putting a liquid in a partial vacuum also will lower its boiling point

Answer 2

Hey Mate Here Is Your Answer

Boiling point depends on pressure. At sea level, water boils at 100 °C (212 °F) and freezes at 0 °C (32 °F). If you boil water at a higher pressure (below sea level, for example), the boiling point would be higher than 100 °C . ... In fact, at the microscopic level, there may be cooler regions of boiling water.
