You are in a mountain range with atmospheric air pressure of 520 , and you wish to boil some eggs. What is the approximate boiling point of the water at this air pressure?

Question

Express your answer as an integer and include the appropriate units.

Answer 1

There may be an easier way to do this (a graph but you didn't say you had one). You can use the Clausius-Clapeyron equation and solve for T2.
ln (p2/p1) = (dHvap/R)(1/T1 - 1/T2)
p1 = 760; T1 = 100
p2 = 520; T2 = ?
dHvap is heat vaporization in J. You'll need to look that up. T2 will be the boiling point of the water at 520 mm Hg pressure.
