why as atmospheric pressure increases,boiling point also
increases?
Answer Posted / balachandran
before answering that I have let me introduce one technical word' vapour pressure'.It is the pressure exerted by the vapour of the concerned substance with that substance at equilibrium.Usually boiling point is determined by prominancy b/w vapour pressure and atmospheric pressure.Suppose water is boiling in an open vessel,let atm prssur be 1 bar.At 1 bar ,boiling point is 100C.suppose this is boiled at a higher altitude,say 1km above sea level.atm presure reduced to .8 bar.but the vapour pressure is still constant for that liquid.Vapour pressure can oppose lower atms pressure easily than a higher atms pressure sothat vapours can easily come out out of the lid.Thus ,a liquids boling point reduces at lower atmospheric pressure.Any confusion still existing ,then mail me to bala300587@gmail.com
