The molecules of gas are in random motion striking with the walls of the containeer in their way if we make a hole in the wall then the no of molecules striking the wall will be allowed to release into the immediate atmosphere. Now u need to look at the no of particles striking that particular area which is

directly proportional to A( /area of hole) P sqrt(T, temp) and 1/sqrt(Molecular mass)
