    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 ?

    What is the average velocity of the molecules of an ideal gas ?

    Assertion: All molecules in a gas are moving with same speed. Reason: Speed of molecules in a gas follows Maxwell's distribution law.

    Assertion (A) : All molecules in a gas have some speed . Reason (R) : Gas contains molecules of different size and shape .

    Assertion (A) : The heat absorbed during the isothermal expansion of an ideal gas against vacuum is zero . Reason (R) : The volume occupied by the molecules of an ideal gas is zero .
