Answer the following ?
(i) Under the conditions do real gases tend to show ideal gas behaviour ?
(ii) What is volume and carbon of Avogadro's number of molecules at `N.T.P.`?
Both propane and carbon dioxide diffuse at the same rate under identical conditions of temperature and pressure. Why ?
(iv) If the number of moles of a gas are doubled by keeping the temperature and pressure constant, what will happen to the volume ?

Explanation

(i) When the pressyr of the gas is very low and the temperature is very high.
(ii) 22.4 L is known as molar volume of the gas.
(iii) Because both propane and carbon dioxide have the same molar mass `(44 g)`.
(iv) Volume will become double since `V prop n` according Avogardo's Law.
