Gas Laws Video: Combined Law
This video demonstrates a solution to a Combined Law problem, involving the variables of pressure, volume and temperature for a confined gas. The problem comes from a warmup set of problems used in class.
NOTE: I assume that you have the use of a periodic table. In working quantitative problems, I will usually round masses to the nearest gram. These examples demonstrate a considerable focus on the rules for simplifying fractions in order to work problems without a calculator.
