Boiling point of Water is 100 °C at 101.33 kPa = 1 Atmosphere
At lower pressures the boiling point temperature reduces.
For example: water boils at 3.8 °C at 0.8 kPa.
At higher pressures the boiling point temperature increases.
For example: water boil at 198.3 °C at 1500 kPa.
Fresh water under atmospheric pressure boils at 100 C or at 212 F
The answer depends primarily on the scale that you are using. On the Celsius (or Centigrade) scale, under normal atmospheric pressure, pure water boils at 100 deg.
Boiling occurs when the vapor pressure is equal to atmospheric pressure. Pure water boils at 1000C at a pressure of 1 bar (1 atmosphere). At lower pressures for example up a mountain at 10000ft 3000m water boils at just under 900C. As you go higher it gets lower still. When salts are dissolved in water the boiling point rises, this phenomenon is termed elevation of the boiling point.
As pressure decreases, the boiling point of water will also decrease. Backpackers camping in the high mountains are familiar with the phenomena when they get water boiling - and find that it is still only lukewarm because the atmospheric pressure at their high altitude is so low.
Water stays at a constant temperature when it boils unless it is under pressure. More heat just makes it boils faster. The boiling temperature is around 212F or 100C varying somewhat with the altitude and the purity of the water.

fresh water under atmospheric pressure
Only if the water is under pressure; that is, at a higher pressure than Earth's atmospheric pressure. This is because 100 degrees Celsius is the boiling point of water (at Earth's standard atmospheric pressure), where any additional heat energy will simply cause the water to vaporize. Under higher pressures, however, the water can be kept liquid to higher temperatures. (The calculation of such pressure is left as an exercise for the student!)
Because that is the temperature at which water boils at the atmospheric pressure at sea level, which is 1 atmosphere. It is the maximum boiling point possible for water unless it is placed under pressure.

Water boils at 100 degrees Celsius or 212 degrees Fahrenheit under standard conditions at sea level (at one atmosphere of pressure).The boiling point of water and any other substance depends on the atmospheric pressure, which changes with elevation. At higher altitudes, the pressure is lower, and so water boils at a lower temperature. If the barometric pressure is not at the standard value, the boiling point will be different. For example, water boils at 72 degrees Celsius on Mount Everest.See the Related Questions links to see how atmospheric pressure and elevation affect the boiling point of water.At 1 atmosphere water boils at:100 oC;373 K; or212 Fahrenheit
Water boils at 100 degrees Celsius under normal atmospheric conditions.
Water boils at 100 C, under normal atmospheric conditions.
100 degrees Celsius is the boiling point of water under normal atmospheric conditions.
Water boils at 121 degrees Celsius under normal atmospheric pressure, which is approximately 1 atmosphere or 101.3 kilopascals (kPa). However, it's important to note that this boiling point is specific to conditions at sea level and can vary based on factors such as altitude and 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.
