graham's law of diffusion with examples

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

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 concentr..

It is a physical process that involves the movement of solute particles from the region of their higher concentration to the region of their lower concentration. Transport of materials within the cell is by diffusion. The entry of carbon dioxide into the stomata is by diffusion..

It is a process, which involves movement of a substance from a region of its higher concentration to a region of its lower concentration. fig. 15.3 - Diffusion Molecules of any substance are in constant random movement in all fluids. This movement is called Brownian movement. Apart from t..

If a bottle of perfume is opened in one corner of a room, it spreads in the whole room by diffusion. If you drop a little ink in a beaker of water it will spread by itself in the beaker of water and the color spreads uniforml..

Colloidal particles like solutes in true solution diffuse from a region of higher concentration to that of lower concentration. Because of their bigger sizes colloidal particles move slowly and diffuse at a slower rat..

When a lead plate and a gold plate are placed one over the other if they are kept under pressure for a period of one or two years. It will be observed that the lead particles have diffused into gold and gold particles have diffused into lead plate. It is believed that fossils o..

If a bottle of perfume is opened in one corner of a room, it spreads in the whole room by diffusion. If you drop a little ink in a beaker of water it will spread by itself in the beaker of water and the color spreads uniformly. Diffusion is the natural process of intermingling..

Kirchhoff's Law - 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 bod..
