The boiling point of water (and all other liquids) is dependent on the barometric pressure. For example, on the top of Mt. Everest water boils at 68 °C (154 °F), compared to 100 °C (212 °F) at sea level. Conversely, water deep in the ocean near geothermal vents can reach temperatures of hundreds of degrees and remain liquid.
higher then the normal boiling point of water
It is because it is cold in a coal mine.
The normal boiling point is the boiling point at sea level, or more precisely, at 1 atmosphere pressure. At higher elevations, or at lower atmospheric pressures, the boiling point is lower. At higher atmospheric pressures, the boiling point is higher.

The boiling point of salt water will be higher - whichever scale is used to measure the temperature. How much higher will depend on the amount of salt that is dissolved in the water.
A tropical climate is not always measured in temperature as it can vary, however, a higher humidity than normal would classify it as tropical.
Yes, at normal atmospheric pressure - a higher temperature is needed at higher elevations. This is offset by some cooks at high elevations by use of a pressure cooker.
The melting point is higher than the boiling point of Arsenic only because the melting point is when Arsenic is under pressure because otherwise it would sublimate, or turn directly from a solid to a gas, a the "boiling" point of 614 degrees Celsius and normal atmospheric pressures.
The boiling point of ethanol whose boiling point is 78.3 degrees Celsius at 760 mm Hg at 650 mm Hg is going to be 75 degrees Celsius. This calculation is done using the clausius-clapeyron equation.
At normal altitudes, pure water boils at 212 degrees Fahrenheit, 100 degrees Celsius.
They are the boiling point of pure water at normal atmospheric pressure.
because it's really 212 degrees Fahrenheit. (:
