1.	The correct statement regarding various types of molecular speeds are
Answer» increasing TEMPERATURE increases the fraction of molecules having `U_(mps)` Increasing temperature increases `U_(mps)` In a SAMPLE of gas at a given temperature, molecules with extremely low and high speeds are less At the same temperature lighter gaseous having narrow DISTRIBUTION of molecular speeds than heavier gaseous Solution :`U_(mp)` increasing with T, but the fraction decreases. Heavier molecules have narrow distribution.
