QUOTE:
By definition, a perfect gas is one in which intermolecular forces are negligible due to the separation of the molecules and any particle collisions are elastic.
Now what I do is use my language skills (which are too poor..so conclusions are subject to market risks.. believe at your own risk :P)
It says: By definition, a perfect gas is one in which intermolecular forces are negligible due to the separation of the molecules... so if the particles lie close to each other, there will be some interaction energy involved unlike Ideal Gases!
no mention about 0 size figure.. I mean to say Ideal gases are more longer on hunger strike and goto gym more often! :D
Perfect gas- I infer is more like real gases less like Ideal.. I mean to say it is a fair approximation of Real gases where we can apply Ideal Gas equation without much deviation from the actual behaviour! [1]
I would hope someone pro expresses his views!
