ing, the water maybe made to boil even when the temperatureis reduced to that of the room. The reason why the boiling point dependsupon the pressure is readily found. Bubblesof vapour begin to form in the liquid onlywhen the pressure exerted by the vapourwithin the bubble balances the pressure… … Fig. 281. —Balance be-tween external pres-sure of the air and thepressure exerted bythe vapour within abubble.
