Winter Park altitude 9100 feet water boils at 91℃

Winter Park, a town in the Rocky Mountains in Colorado, has an altitude of 9100 feet. Water (ΔHvap = 40.7 kJ/mol) boils at 91℃ in Winter Park. What is the normal atmospheric pressure in Winter Park?

> P1 = ? atm, T1 = 273.15 + 91 = 364.15 K

> P2 = 1 atm, T2 = 273.15 + 100 = 373.15 K

Clausius-Clapeyron 식

ln(P1 / P2) = ΔH_vap/R (1/T2 – 1/T1)

( 참고 https://ywpop.tistory.com/3133 )

ln(P1 / 1) = (40700 / 8.314) (1/373.15 – 1/364.15)

P1 = e^[(40700 / 8.314) (1/373.15 – 1/364.15)]

= 0.723 atm

답: 0.72 atm
