principles of diffusion in gas

The molecules of the gas are in constant motion, at very high velocity. There is a great amount of intermolecular space between the molecules. When two gases are mixed, particles of one gas can easily pass through the intermolecular space of the other gas. As a result..

Gases have the tendency to spontaneously intermix and form a homogenous mixture without the help of external agency. This is due to the presence of large amount of empty space between the gas molecules that makes their movement rapid into each other. The gases move from a region of ..

From kinetic theory, Since the rate of diffusion of a gas is determined by the molecular speed,..

By Synthesis - Hydrogen chloride gas can be prepared by the direct combination of hydrogen gas and chlorine gas in the presence of sunlight. The reaction is explosive in direct sunlight. However, in diffused sunlight the reaction is slow and controllable. In ..

Let us consider the case of electromagnetic radiation in an ionised medium. Suppose we increase/decrease the amplitude of an electromagnetic wave passing through an ionised gas. These modulations of the electromagnetic wave could contain coded information (Morse code for example). One wo..

Summary - Gases are different from solids and liquids. They have no definite shape or volume. When pressure is applied, a gas contracts and when pressure is released, the gas expands. Gases can move in all directions and completely diffuse with other gases to form a ho..

Let the rate of diffusion of oxygen be r(O 2 ) = r 1 The rate of diffusion of the unknown gas r (x) = 4r Molecular mass of O, M(O) = 32 Molecular mass of unknown gas M (x) = M From Graham's Law of diffusion,..

As seen from equation (1-28), the velocity of sound in a gas depends on g , the ratio of the principle specific heats of the gas. This, in turn, depends on the atomicity of the gas..
