The weight of the mass added to the hanger is equal to the extra force on the gas, but what area should we use to calculate the added pressure from this mass?
With some of the experimental details out of the way, let's think a bit about what we expect to see in our data if the ideal gas law is a good model for our gas. We would like to verify the ideal gas law PV = nRT
