Question

the lower fixed point is the temprature at which pure water boils at the sea level true or false​

                                   Sort type answer

Boiling point, temperature at which the pressure exerted by the surroundings upon a liquid is equaled by the pressure exerted by the vapor of the liquid; under this condition, addition of heat results in the transformation of the liquid into its vapor without raising the temperature

                                    long type answer

At any temperature a liquid partly vaporizes into the space above it until the pressure exerted by the vapor reaches a characteristic value called the vapor pressure of the liquid at that temperature. As the temperature is increased, the vapor pressure increases; at the boiling point, bubbles of vapor form within the liquid and rise to the surface. The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapor pressure is equal to the standard sea-level atmospheric pressure (760 mm [29.92 inches] of mercury). At sea level, water boils at 100° C (212° F). At higher altitudes the temperature of the boiling point is lower. See also vaporization....
