Problem: One gram mole of oxygen at 27°C and one atmospheric pressure is enclosed in a vessel. (a) Assuming the molecules to be moving with vfind the number of collisions per second which the mol ecules make with one sqaure metre area of the vessel wal. (b) The vessel is next thermally insulated and moved with a constant speed v, It is then suddenly stopped. The process results in a rise of the temperature of the gas by l°C. Calculate the speed v,. |IT-JEE : 1983
