In this chapter, we have seen how arranging numbers in orderly rows and columns under the guise of Matrices and Determinants, has helped to solve linear equations or find the area of a triangle. There are in fact other much wider applications in Science and Engineering and other fi..

We have seen the application of matrices and determinants in solving system of linear equation with three unknown variables. Matrices and determinants are also widely used in solving large system of linear equation. Some of these methods are Gauss-elimination method, Gauss-Jordan method etc. They a..

Since all gases form cathode rays, it means that all atoms contain electrons. As the cathode ray particles were negatively charged, an electron was also carried a negative charge. The following processes were also found to emit electrons: a) The action of heat on certain metals. b) The action of ul..

Presence of dangerous unnatural ingredeints causing imbalance in the ecosystems and health hazards to human beings and animals is called pollution. Pollution is mainly found in air, water, soil, food and sound. Major human activities like industries, agriculture, health care, transport, dwe..

Respiration is an important process in nature. It is a process by which the solar energy trapped by the plants in the food can be utilised. The organic compounds are broken down to release energy. This energy is in the form of ATP molecules and is made available for all the vital activities of the ..

Nucleus of an atom is positively charged Nucleus is very dense and hard Nucleus is very small compared to the size of the atom. ..

In this chapter on chemical bonding, we have learnt the meaning of chemical bonding, need for bonding, and the different types of chemical bonding: ionic, covalent, polar covalent and coordinate bondi..

Currently, 106 elements are known to the human kind. The number of carbon compounds alone is much more than the number of compounds of all remaining 105 elements put together. The number of carbon compounds known to man is around 600,000 whereas the number of the compounds of all the remaining comp..

Rate of reaction usually doubles when the temperature is raised by ten degrees near the normal temperature because the rate constant is dependent on temperature. The temperature dependency of rate constant is mathematically expressed by the Arrhenius equation. Arrhenius equation is an empiric..

Transition elements are known for their ability to form many complex compounds. The complex compounds in which the metallic ion is surrounded by two or more ions or molecules are called coordination compounds, also known as complex compounds. The chapter has covered the nomenclature, isomeris..
