Area is pi* r^2 , so to calculate the uncertainty of a squared value, we multiply it by 2m so 8%
Better?

Good job dude :)

You may look here as well for the electromagnetic spectrum. (click on electromagnetic spectrum in the index on your right ) ;)

Internal energy = PEs + KEs

since ideal gas does not have intermolecular forces of attraction PE =o

Internal energy= KEs
                     = number of gas molecules * KE of one atom
