This chemistry video tutorial provides a basic introduction to pressure. Pressure is defined as force per unit area. 1 Pascal equals 1 Newton of Force per square meter of area. This tutorial gives you an example of calculating the pressure exerted by a book on the table using the weight force of the book and its cross sectional area. This lecture also discusses the inverse relationship between elevation and atmospheric pressure. As the elevation increases, the atmospheric pressure decreases and the boiling point of water decreases. It's easier to boil water on a mountain since the air pressure is so low but it's harder to boil in a valley that is below sea level. This video also considers the gases that make up the atmosphere. Heavy gases tend to sink down and lighter gases rise. In addition, hot air rises and cold air descends.
