Look, I've tried to be nice here, but you keep insisting that you’re right when it's clear that you have absolutely no f***ing idea what you're talking about. Read a basic chemistry textbook. The vapor pressure of a liquid increases as temperature increases. If the vapor pressure of a liquid is greater than the atmospheric pressure around the liquid, that liquid will boil. That's why you have to heat water to boil it - you are heating it to raise its vapor pressure. If the atmospheric pressure is lower, then you don't have to heat the liquid as much to get it to boil because it doesn't have to attain as high a vapor pressure in order to start boiling. If you increase the atmospheric pressure on a liquid to above 1 atm, you now have to heat the liquid above 100 C to get it to boil. If you take a pot of water to the top of a high mountain, it will boil at less than 100 C because the pressure is lower. I don't know how I could make this any more explicit.
