ains on the mercury and ceases to furtherevaporate, it is said to have reached its pointof saturation, or maximum tension, or limitof tension. In this case, the tension of thevapor balances the tendency of the liquid topass into a state of vapor. Yet the quantityof watery vapor necessary to… … HEAT. 183 Fig. 28. Tlie limit of tension of a given vapor varies with the temperature. The amount of vapor required to saturate a given space also varieswith the temperature. liain is caused by the vapors (whicli are less dense than the air inlow regions) rising to regions where they are condensed…
