1.	Which of the following statements do you think is the correct one?(a) in gases there is a predominance of intermolecular energy(b) all molecules have the same speed at different temperatures(c) collisions of gas molecules are elastic(d) do not exert the same pressure in all directionsI had been asked this question in class test.The doubt is from States of Matter topic in division States of Matter of Chemistry – Class 11
Answer» Right choice is (C) collisions of gas molecules are elastic Easy explanation: Collisions are elastic as the TOTAL amount of energy before and after the collision is the same. The correct STATEMENTS of the incorrect ones are: in gases, there is a PREDOMINANCE of thermal energy, the distribution of SPEEDS remains constant at a particular temperature and the gases exert the same pressure in all directions of the container.
