An ideal gas or a perfect gas is that which strictly obeys the gas laws (such as Boyle's Law, Charle's Law etc.) Two essential characteristics of an ideal gas are : (i) size of molecule of an ideal gas is zero. (ii) There is no force of attraction or reputation amongst the moleculess of an ideal gas. In view of this, no real gas is perfect. Read the above passage and answer the following questions : (i) Under what conditions do same real gases behave as nearly perfect gases ? What does this concept imply in day to day life ?

1.	An ideal gas or a perfect gas is that which strictly obeys the gas laws (such as Boyle's Law, Charle's Law etc.) Two essential characteristics of an ideal gas are : (i) size of molecule of an ideal gas is zero. (ii) There is no force of attraction or reputation amongst the moleculess of an ideal gas. In view of this, no real gas is perfect. Read the above passage and answer the following questions : (i) Under what conditions do same real gases behave as nearly perfect gases ? What does this concept imply in day to day life ?
Answer» Solution :(i) At extremely LOW pressure and high temperature, some REAL gases like helium, hydrogen, OXYGEN, etc. Behave as nearly perfect gases. (ii) in day to day life, this concept impliesthat none of us is perfect. Only rarest of the rate who has PRACTISED totalrenunciation can be taken as nearly perfect. such a person has REDUCED his size to zero, as he has merged himself with God Almighty . He has no individual identity and there is no question of force of attractions (raga) and repulsion(dwesha) with respect to him.
