. Second law of thermodynamics states that processes of energy transformation will not occur spontaneously unless there is degradation of energy from a non - random to a random form. Energy transformations, which occur within the ecosystem are considered in ecological energetics..

When more than one type of molecule is present (at constant T) then, the total pressure exerted by the mixture should be equal to the sum of their individual pressures when present alone. The pressure exerted by each gas is..

Coulomb's Law - It states that "the electrostatic force between two electric charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them ..

Proposed by Dalton in 1803, this law states that: 'When two elements combine to form two or more compounds, then the different masses of one element, which combine with a fixed mass of the other, bear a simple ratio to one another'. This law is evident when one elemen..

The Second Law of Thermodynamics - Experimental evidence suggests strongly that it is impossible to build a heat engine that converts heat completely to work (an engine with 100% thermal efficiency). This impossibility is the basis of one statement of the second law of..

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 each other. The gases ..

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 homogenous mixture. Gases have l..

This law is used to add more than two vectors. The above figure illustrates four vectors Each of these vectors is displaced parallel to itself so that all four of them touch each other as shown in the figure (b). Obviously vector will be the resultant of . Thus, the law c..

The Biot - Savart's law enables us to write the general results for the magnetic field due to an arbitrary current distribution or it is an experimental law predicted by Biot and Savart dealing with magnetic field strength at a point due to a small current element. If AB repre..

Assumptions stated by Classius - All the molecules of a gas are identical with respect to their shape and mass. The molecules of different gases are different. The gas molecules behave as rigid, elastic and smooth spheres. The size of gas molecules is very less when compared to the interm..
