Boiling Point vs. Atomspheric Pressure The boiling point of water depends on atmospheric pressure. At high altitudes, atmospheric pressure is lower, and hence water boils at a slightly lower temperature. Plot a graph by hand for the following data treating atmospheric pressure as the independent variable.

1. The normal (at 760 mmHg, or 1 atm) boiling point of water is 100°C. What mass of glucose (C6H202) would you have to dissolve in 1000 g of water to decrease the vapor pressure at 100°C by 1%? Assume that water follows Raoult's law. M(H2O) = 18.02 g/mol, M(C6H1206) = 180.2 g/mol. (10 pts) 2. What is the normal boiling point of such a solution? Assume ideal behavior. The ebullioscopic (boiling-point elevation) constant of water is Kp = 0.512...

II Revi Part A The vapor pressure of a substance describes how readily molecules at the surface of the substance enter the gaseous phase. At the boiling point of a liquid, the liquid's vapor pressure is equal to or greater than the atmospheric pressure exerted on the surface of the liquid. Since the atmospheric pressure at higher elevations is lower than at sea level, the boiling point of water decreases as the elevation increases. The atmospheric pressure at sea level...
