graham law of diffusion

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

Graham's Law of Diffusion - 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 ea..

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 higher con..

A body that is a good radiator (or emitter) is also a good absorber. To understand this, suppose isotropic (i.e., equal in all directions) thermal radiation is incident on a body. Let a be the fraction of the total thermal radiation of all wavelengths absorbed by the body. The remaining fraction is..

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,..

Of the three states of matter, the gaseous state is the simplest and shows greatest uniformity in behaviour. Gases show almost similar behaviour irrespective of their chemical nature. This state is characterized by: Gases maintain neither the volume nor the shape. They completely fill the container..

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 homogenous mixture. G..

. When sound becomes so intense that it is painful to the ear, the amplitude is of the order of 1-2mm. The loudness of sound is defined as the degree of sensation of sound produced in the ear. The loudness of sound depends on its intensity but the relationship is not linear. It obeys an approximate..
