When the boiling point of water greater than or less than a standard atmospheric pressure is lower than a standard atmospheric pressure
Boiling point increases when it is greater than one standard atmospheric pressure, and decreases when it is less than one standard atmospheric pressure
The reason why the boiling point of water is 98 degrees may be that it is below standard atmospheric pressure
Do you need to ask? Water boiling point 100 degrees refers to the boiling point at a standard atmospheric pressure. Below the standard atmospheric pressure the natural boiling point is also reduced
Do you need to ask? Water boiling point 100 degrees refers to the boiling point temperature at a standard atmospheric pressure. Below the standard atmospheric pressure the natural boiling point is also reduced
