Jay students, in this question you have to see the difference between diffusion and effusion and how effusion data f gas is proportional to or related to molar mass of the gas.
00:12
Now first coming to diffusion, diffusion is nothing but the tendency of intermixing of, it is the tendency of intermixing of non -reacting gases, non -reacting gases, spontaneously, spontaneously without external pressure, without external pressure.
00:56
So it is a spontaneous tendency.
00:59
So intermixing of non -dating gases, two or more non -dating gases, spontaneously without external pressure is known as diffusion.
01:07
But effusion is the property of the flow of gas molecules, property of, property of flow of gas molecules, from high concentration to low concentration.
01:38
From high concentration to low concentration through a pinhole with external pressure.
01:56
Through a pinhole with external pressure.
02:06
So this is the main difference between diffusion and diffusion.
02:09
In diffusion, there is no need of external pressure...
