Fresh water under atmospheric pressure boils at 100 C or at 212 F
At atmospheric pressure, fluorine boils at -188.13 °.
It depends on other conditions, such as the pressure, and the purity of the water. However, at normal atmospheric pressure, pure water boils at 100oC. As an example of the importance of pressure, consider that it boils at just 65oC at the summit of Mt. Everest. This is why you can't get a decent cup of tea up there!
Water boils when its internal pressure reaches that of the atmospheric pressure. Therefor, if one lowers the atmospheric pressure, the water would boil at a lower temperature (in fact, one can make water boil at room temperature by dramatically lowering the atmospheric pressure).
The lower the pressure then the lower the temperature that is required to make it boil. Water at the top of Mount Everest boils well below 100 degrees centigrade due to the lower atmospheric pressure.
This is not a cut and dry answer. The temperature that water evaporates to a gas and conversely condenses to a liquid is dependent on air pressure. Liquid boiling points can also be affected by impurities in the liquid, depending on the concentration of impurities. Thus in a pressure cooker water boils at a much higher temperature that it would under normal atmospheric pressure. This is also why you can't make a decent cup of tea on the summit of Everest because water boils at about 71 degrees Celsius at that reduced atmospheric pressure. So it is impossible to give a specific figure for this question.
The atmospheric pressure is lower. When you are boiling the water, the water's vapour saturation pressure is able to match the atmospheric pressure faster therefore it boils faster and at a lower temperature.
at normal atmospheric temperature (in plains) it boils at 100oC
Water boils at 100 degrees Celsius at sea level, or at standard atmospheric pressure.
At Muree hills the pressure of air is 700 which is less than 760 torr so water boils at 98 degree centigrade and at Mount everest pressure further decreases and water boils at 69 degree centigrade
there is less atmospheric pressure than at sea level
Pure water boils at 100 degrees at atmospheric pressure.
