The Ideal Gas Law: pV = nRT - IB Physics

Lecture on the definition of an ideal gas:    • What is an Ideal Gas? The Kinetic Mod...  
'
In this lecture I:
-Give the Ideal Gas Law equation, define each variable (pressure p, volume V, number of moles n, the Ideal Gas Constant R, and absolute temperature T) and show how to calculate and work with each. I also give each unit and explain why the temperature has to be on an absolute scale.
-Give examples of each type of graph where all but two variables are held constant: pressure vs temperature graphs, volume vs temperature graphs, and pressure vs volume graphs. I also use animations to show what these graphs physically represent
-Show why the Ideal Gas Law can ONLY apply when we are working with an ideal gas (why the conditions for an Ideal Gas are also the conditions for the Ideal Gas Law to be used)real gas equation
-Conclude with examples of graph problems, math problems, and proportional reasoning problems using pV = nRT
