Answer 1

"First of all, I explain you that ""As elevation increases, atmospheric pressure decreases because air is lens dese at higher altitudes Bemuses the atmospheric pressure is lower the vapor pressure of liquid needs to be lower to reach boiling point Therefore lessthanorequalto heat is required to make the vapour pressure equal atmospheric Now In Question Air pressure at a particular plane in the[pols = 0.47 atm] we have to find Boiling point of water we current air pressure from atm to mm Hg Pols = 357.199 mm Hg [pols = 357.199 mm H g] so From the Knowledge of them dynamics observed Boiling point of water at mountain will (BP)_obr = (BP)_at secular + [pols - 760 mm Hg 1 times 0.045 degree C/mm Hg] = 100 degree C + (- 402.801 times 0.045) degree C = 100 degree C - (8.1260) degree C = 100 degree C - (18.1260) degree C [(BP)_obs = 81.8739] \r\n what is Dew point ? It is the temperature to which air must be cooled to become saturated with water vapor when further cooled the airbase water vapor will condense to form liquid water (dew) when air cools to its dew point through"
