• The (3 points) part of your question is a pretty good giveaway that you copied this question from somewhere. Could you share what your thoughts on this question are? – Ben Norris Aug 31 '16 at 10:31
• Actually I was studying my textbook which is the NCERT for class 11 in India. In which there is this question. I added 3 points because my teacher asked the same question - Give 3 points while taking a viva examination. – S Aditya Aug 31 '16 at 12:00
• Further it didn't click me that I had to write about the assumptions that were taken by Maxwell and Boltzmann while formulating the kinetic theory of gases... I was trying to relate this question to the trend of compressibility factor of real gases vs ideal gases. – S Aditya Aug 31 '16 at 12:06
