Problem
One gram mole of oxygen at 27∘ and one atmospheric pressure is enclosed in a vessel.
(1) Assuming the molecules to be moving with Vrms , Find the number of collisions per second which the molecules make with one square metre area of the vessel wall.
(2) The vessel is next thermally insulated and moved with a constant speed V0 . It is then suddenly stopped. The process results in a rise of the temperature of the gas by 1∘C . Calculate the speed V0 .
