Explanation Given The atmospheric pressure in Colorado Springs is 58 2 torr . The enthalpy of vaporization of water is 40 .7 kJ/mol . The vapor pressure of a water changes with temperature. The relationship of vapor pressure of water at two different temperatures and enthalpy is, ln ( P 1 P 2 ) = Δ H ¯ R ( 1 T 2 − 1 T 1 ) (1) Where, • P 1 is the vapor pressure at temperature T 1 . • P 2 is the vapor pressure at temperature T 2 . • R is the universal gas constant ( 8.31 4 J/K/mol ) . • Δ H ¯ is the change in enthalpy. The initial temperature, T 1 is 10 0 ο C . The conversion of Celsius to Kelvin is done as, 0 ο C = 2 73 K Therefore, the conversion of 100 ο C to Kelvin is done as, 100 ο C = 100 + 2 73 K = 373 K The initial pressure, P 1 is 760 torr

Ideal and Real Gases

Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,

Gas Laws

Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries we…

Gaseous State

It is well known that matter exists in different forms in our surroundings. There are five known states of matter, such as solids, gases, liquids, plasma and Bose-Einstein condensate. The last two are known newly in the recent days. Thus, the detailed fo…

Question

Chapter 6, Problem 6.43E

Interpretation Introduction

Interpretation:

The boiling point of water in Colorado Springs is to be calculated.

Concept introduction:

The temperature at which the liquid state of a compound changes to the vapour state is termed as boiling point of the substance.

The temperature, at which the liquid boils at a pressure of one atmosphere, is known as normal boiling point.
