Which of the following is not a postulate of Kinetic molecular theory

1.	Which of the following is not a postulate of Kinetic molecular theory of gases?(a) the actual volume of gas molecules is negligible(b) there are high forces of attraction between the gas molecules(c) collisions are elastic in gas molecules(d) kinetic energy of gas molecules is directly proportional to the absolute temperatureThe question was asked during an internship interview.My doubt is from States of Matter topic in portion States of Matter of Chemistry – Class 11
Answer» Right answer is (b) there are high forces of ATTRACTION between the gas molecules The best explanation: According to Kinetic molecular THEORY of GASES, there are no forces of attraction between the particles of gas at normal temperature and pressure. This is because gases expand and occupy all the SPACE available.
