Problem 8 Because pressure falls with increasing altitude, water also boils at a lower temperature. Consequently, food generally require more time to cook at higher elevations. Determine the boiling temperature of water at sea-level, 1000 m, and 2000 m above sea-level. Assume standard atmospheric conditions.

Answer #1

The boiling point of water decreases with altitude.

the boiling point of water at an altitude of 1000 m from sea-level is 96.4oC.

the boiling point of water at an altitude of 2000 m from sea-level is 93oC.

In the curve which is drawn between the boiling point on y axis, and the altitude on x-axis. then the curve is linear with negatve slope.(from experimental analysis)

in case of any doubt, please do commment sir.

Values are inferred from the graph

    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...

    "Vapor Pressure of Water" assignment: VAPOR PRESSURE OF WATER INTRODUCTION All liquids exist in equilibrium with the vapor state. As temperature increases, this equilibrium shifts more and more in favor of the vapor until one reaches the boiling point, at which all liquid is converted to gas. The pressure exerted by the vapor over the liquid is known as its vapor pressure and is a function of temperature. Boiling occurs at the temperature at which the vapor pressure is equal...
