The controlled combustion of fuel in the presence of air, gives an internal combustion engine its power. A low quality fuel does not burn smoothly and causes an occasional explosive sound, which is known as knocking. This greatly reduces the power of the engine. The quality of a fuel is indicated ..

An atom is a very minute particle and so the actual mass of an atom is extremely small. It is physically not possible to measure such small masses easily. In 1811, Avogadro suggested that atomic and molecular masses can be expressed on an atomic mass scale relative to that of a standard reference ..

It is not possible to measure the absolute potential of a single electrode because neither the oxidation nor the reduction reaction can occur by itself. Also, we need two electrodes to measure the potential difference between two points. This difficulty can be solved selecting one of the electrodes..

Let S be a sample space associated with a given random experiment. A real valued function X which assigns to each w i S, a unique real number, X( w i ) = x i is called a random variable . Two types of random variables are 1. Continuous random variable, 2. discrete ra..

An indirect method to determine the absolute mass of an atom has been devised. The mass of a particular atom is taken as a standard unit and the masses of other atoms are related to this standard. Hydrogen being the lightest element and being the smallest atom was chosen and assumed to have a mass ..

The numbering of carbon atoms in the ring (or nucleus) is done as follows. When there is only one substituent on the ring, there is only one compound possible. Thus, numbering of the carbon atoms of the nucleus does not arises. If there are two or more substituents, then numbering is in the alp..
