Document Summary
I get an hour of sleep, you get an extra hour to study for the final. Ideal gas law is accurate to ~1. 5% for gases under 20 atm and 50 c above their boiling points. Molar volume at stp vm = 22. 414 l. Stp = standard temperature and pressure (for gases) Essentially, we are plotting the deviation from the ideal gas law. The closer a gas is to the liquid state the more it will deviate from the ideal gas law. Corrections to describe the behavior of gases are called equations rather than laws. These equations are good for limited ranges but within those ranges are better than the ideal gas law. Most corrections account for the finite volume of the molecules and for the attractive forces between the molecules. The most famous equation is the van der waals equation. an2. V2)(v nb) = nrt (p + an2.
