1.	Assertion : The root mean sguar and most probable speed of the molecules in a gas are the same Reason : The Maxwell distribation for the speed of molecules in a gas is symentricalA. If both assertion and reason are true and the reason is the correct explanation of assertion.B. If both assertion and reason are true but reason is not the correct explanation of assertion.C. If assertion is true statement but reason is false.D. If both assertion and reason are false.
Answer» Correct Answer - d Root mean squre speed of moleclues in a gas is define as the equal root of mean of space of the speed of difference i.e. `v_(min) = sqrt(((v_(1)^(2) + v_(2)^(2) + ......)/(N))` `or v_(min) = sqrt((3RT)/(M))` (according to kinetic theory gases) while most position speed is the speed which maximum number of molecles in a gas have at common temperature and is given by `v_(m) = sqrt((2RT)/(M))` It is abvious that `v_("rms") gt v_("mp").` Also maxwell damenation for the speed of moleculas in a gas is any numerical hence option (d) is true.
