THE BOILING POINT IS HIGHER for compounds with strong intermolecular forces, or the boiling point is higher for compounds with a high viscosity, or the boiling point of a compound is higher for nonvolatile compounds, or the boiling point of a compound is an absolute constant, or all of them are TRUE

Just one example to demonstrate that the last statement is false:

The boiling point certainly isn't an absolute constant -- as those of us out here in the mountains of Colorado can tell you! Rather than 212F (100C), it's not unusual to be at an altitude in this state where water boils at 200F, or even as low as 185F if you really like to climb our "14ers".

You really don't need a Rocky Mountain High experience for this, either. Even minor changes in local barometric pressure will cause the boiling point of water to shift a bit. It's true for a great many other compounds as well.

I'll give you a "boy, was that stupid" example, too!

Filled a good quality thermos with hot coffee right off the stove in K.C., altitude about 900 feet. Drove directly down to the airport and hopped into a Cessna 210 and headed north to visit the relatives. At about 8000 feet, opened the thermos, forgetting to do it SLOWLY. Due to the large decrease in air pressure at altitude, had a face/lap full of very hot coffee as it immediately boiled upon opening! OUCH!

Hi. The boiling point of a compound is an absolute constant is false. Water changes it's boiling under different pressures.

The guys are right and Jeffry is in principal right too, but the the statement says: "the boiling point of a compound is higher for NONVOLATILE compounds.

it is FALSE that the boiling point of a compound is an absolute constant, because boiling point will depend on atomospheric pressure. the boiling point of water is less at higher altitueds becasue there is less atmospheric pressure pushing down on the water.
