Mexico City has an elevation of 7400 ft above sea level. Its normal atmospheric pressure is 589 mm Hg. At what temperature does water boil in Mexico City?
Given that the volume and amount of water are kept constant, P/T = constant P₁/T₁ = P₂/T₂ Normal atmospheric pressure is 746 mmHg and normal boiling point of water is 100 °C. 746/100 = 589/T₂ T₂ = 79.0 °C
