Applications of Archimedes' Principle - A floating ship displaces water equal to its own weight, including that of carg..

The state of equilibrium in any system depends upon factors present in the system, such as temperature, pressure and concentration of various species. These factors are called reaction variables or parameters. A change in any one of the parameters may affect the position of the equilibrium. The gen..

Fundamental Principle of Counting - Suppose two events E 1 and E 2 are to be performed in sequence, then if E 1 can be performed in 'm' ways and for each of these ways E 2 can be performed in 'n' ways, then the sequence E 1 E 2 can be performed in 'mn' different ways. This is known as the..

Archimedes' Principle - The underlying fact on which the principle is based was discovered by Archimedes in about 300 B.C. The story goes that the King of Sicily suspected that the goldsmith has mixed some silver in his crown and cheated him. Without destroying the crown he want..

General Principles of Organic Nomenclature - Organic chemistry deals with about 5 million compounds containing carbon as an essential element. Remembering the name of each individual is not possible. Therefore, a system of nomenclature has been devised to name these compounds. Two commonl..

Principle of Mathematical Induction - If P(n) is a statement (n N); such that: P(1) is true and truth of P(k) implies the truth of P(k+1), then by the principle of mathematical induction (P.M.I.), the statement P(n) is true for n ..

Suppose two events E 1 and E 2 are to be performed in sequence, then if E 1 can be performed in 'm' ways and for each of these ways E 2 can be performed in 'n' ways, then the sequence E 1 E 2 can be performed in 'mn' different ways. This is known as the Fundamental Principle of Countin..

It is a matter of common experience that bodies appear lighter when immersed in water or any other liquid. While bathing we notice that the mug of water suddenly appears heavier as soon as it comes above the water surface. Similarly, when a fish is pulled out of water, it appears to be heavier in a..

If P(n) is a statement (n N); such that 1. P(1) is true and 2. truth of P(k) implies the truth of P(k+1), then by the principle of mathematical induction (P.M.I.), the statement P(n) is true for n ..
