At the boiling point of a liquid, the liquid's vapor pressure is equal to or greater than the atmospheric pressure exerted on the surface of the liquid. Since the atmospheric pressure at higher elevations is lower than at sea level, the boiling point of water decreases as the elevation increases. The atmospheric pressure at sea level is 760 mmHg.
First, let's say we have a compound with a boiling point of 100oC at 1mm Hg pressure. What is the boiling point at 760mm Hg? To do this we need to draw a line from 100oC on scale A (left side, observed boiling point) to 1.0 mm Hg on scale C (right side, pressure "P" mm). We can then read off the boiling point at 760 mm on line B, it is about 280oC.
Absolute zero, temperature at which a thermodynamic system has the lowest energy. It corresponds to minus 273.15 degrees Celsius and to minus 459.67 degrees Fahrenheit. While all molecular movement does not cease at absolute zero, no energy from that motion is available for transfer to other systems.

There is no such thing as a single fixed boiling point for mixtures such as petrol, kerosene or the butane/propane mix: the mixture 'boils', but the boiling point changes as the components boil at different rates. Why? because the liquids are only mixed, not dissolved in each other.
The vapor pressure of a polar compound like a low-molecular weight alcohol has a greater temperature dependence (enthalpy of vaporization) than a non-polar compound like an alkane. So an alkane and an alcohol with the same boiling point at one atmosphere will not have the same boiling point at another pressure.

Jun 01, 2007 · Not to nitpick, but the point of a pressure cooker is to NOT steam food - or, rather, to not boil your water off. By increasing the pressure, water can be maintained in a liquid state at higher temperature than would be possible at atmospheric pressure. g. The orifice opening is larger for the low pressure gas to allow the proper flowput since the psi is normally around 3 to 6. . Oct 01, 2012 · Gas, whether natural or propane is pressure regulated. The Ward System uses 2500 Btus per cubic foot of propane at 60 degrees F. Gas boilers use natural gas or propane to heat water to its boiling point. The pressure and high temperatures in the deep underground gas reservoir means that some low boiling point hydrocarbon compounds (which would be liquids at normal temperatures and pressures above the ground) become gases under the ground. Propane has a low boiling point so it is more suited for colder environments. It evaporates at -42°C at atmospheric pressure. Butane doesn't burn well at lower temperatures, it evaporates at around 0°C at atmospheric pressure. The basic relationship between pressure and boiling point is at the heart of any discussion of the refriger-ation cycle.The boiling point of a liquid is affected by the pressure exerted on its surface. For example, the boiling point of water is 212°F at sea level pressure (generally accepted as 14.7 psi). The corresponding temperature is 46 deg C (114.8 deg F), and that is the dew point of this sample. 4. For 20 percent water, a vapor pressure of 152 mmHg would be indicated. By reference to the table, the dew point is seen to be somewhere between 60 and 61 deg C (140-141.8 deg F).
