. When the rate of adsorption equals the rate of desorption, dynamic equilibrium is attained. If q is the fraction of the total available surface covered with gas molecules, at any instant, then (1- q ) is the fraction of the surface of the solid which is empty. From kinetic the..

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 h..

In earlier times Air was considered as an Element but it was found out to be a mixture. The following are the reasons for considering air as mixture and not an element or a compound. a) Air has a variable composition and hence it cannot be represented by a chemical formula. The percentage compos..
