Calculating Boiling Point Using Clausius Claperon Equation

[anirudh dutta]

Homework Statement

cal the boiling point of water at 300m. assume its 100 degree centigrade at sea level. given g, R, T=300K, molecular weight of air is 29g/mol and latent heat of evaporation is 540 cal/g at STP

Homework Equations

The equation is

dp/dt= L/T(v₂-v₁)

where v is the specific volume of water at temp 1 and temp 2

The Attempt at a Solution

i was able to calcutale dp as it ρgh. i m stuck what to do with v2-v1 part

 

[rude man]

Consider the relative numbers involved with v₂ vs. v₁. Simplify the equation accordingly.

Then think about the ideal gas law.
