Vapor Pressure of a Mixture: Raoult's Law   
(Movie/Animation, Audio/Visual (2))
The measurement of pressure exerted by a vapor is demonstrated using barometers. Vapor pressure varies with the strength of the intermolecular forces in the liquid. In this section we will look at vapor pressure of mixtures. We can calculate the vapor pressure of a mixture using Raoult's law.

Steam and Superheated Steam   
(Movie/Animation, Audio/Visual (2))
Water is boiled and the steam is collected and run through a coil of copper tubing. When a gas burner heats the steam coil strongly, the steam becomes superheated and is at a high enough temperature to ignite a match and react quickly with steel wool.
Boiling by Cooling   
(Movie/Animation, Audio/Visual (2))
A flask contains water and water vapor at 100C. Each time ice water is poured over the outside of the flask, the water inside the flask boils. Although the temperature of the water in the flask has decreased, in each instance boiling is observed.

Two Balloons (GCMP)   
(Interactive Simulation, Software (1))
Two Balloons: this is a resource in the collection "General Chemistry Multimedia Problems". In the Two Balloons video, the left flask contains some water and the right flask contains only air. What do you see when balloons are fastened to the mouths of the hot flasks? General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.

Although ozone is an important component of the upper atmosphere, long-term exposure to ozone in the air we breathe can cause inflammation of the lung, impairment of lung defense mechanisms, and irreversible changes in lung structure. The EPA has set an 8 hour limit for ozone of 0.08 ppm as an air quality standard for cities. At the EPA limit, how many ozone molecules are present in 5.0 liters of air at 25oC and 0.967 atm? (Hint: assume that air is an ideal gas and calculate the total number of molecules there are in 5.0 L. Then use the definition of ppm.)
