1.	The density of a gas a is twice that of gas B. Molecular mass of A is half of the molecular of B. The ratio of the partial pressures of A and B is :A. `1//4`B. `1//2`C. `4//1`D. `2//1`
Answer» Correct Answer - C `PV = nRT` `P = (wRT)/(Mv) = (dRT)/(M)` `(P_(A))/(P_(B)) = (d_(A))/(d_(B)) xx (M_(B))/(M_(A)) = 2/1 xx 2/1` `= 4//1`

The gases obey the different gas laws only theoretically. Practically all of them show some deviation from these laws. These are called real gases. The deviation are maximum under high pressyre and at low temperature. These are comparatively small when the conditions are reversed. It has been found that the easily liquefiable gases show more deviations from the ideal gas beheviour as compared to the gases which are liqufied with diffculty. Gas deviates from ideal gas beheviour because moleculesA. are coloulessB. attract each otherC. contain covalent bondD. show Brownian Movement.
