As per KTG, molecules in gaseous state are under continuous motion with no intermolecular forces occurring & the speed of the molecules will keep on changing due to the molecular collections. The distribution pattern remains constant and is given by `(dN)/(du) = 4 pi N (M/(2 pi R T))^(3/2) u^2 . e^((-Mu^2)/(2RT))` (symbols have usual meaning). The collisions are assumed to be perfectly elastic. In case there are more than one gas in the container then also presence of one type of gas will not affect movement of other gas than one gas. Based on this information, answer the question that follows. A closed container fitted with a movable piston always operating at fixed pressure is subjected to increase in temperature. Identify the correct option assuming a single gas to be present in the container.A. Number of collisions made by any one molecule in one second will be directly proportional to root of absolute temperature.B. Mean free path will increases linearly with absolute temperatureC. Total number of BMC in one second will increases.D. Average speed of approach will remain unaffected.
