The electric power line enters our house through three wires. One is called the earth wire or ground wire. This carries no electricity. The earth wire is connected to a large metal plate buried deep in the ground. The remaining two wires carry electricity. One of these is maintained at zero potenti..

If a quantity y varies with respect to another quantity 'x' satisfying some rule y = f(x), in other words if y is a function x, then represents the rate of change of y with respect to..

The criterion for a chemical change is the production of one or more new substances. Therefore, certain conditions should be met in order to bring about a chemical change. The necessary conditions are: 1) A minimum amount of energy needed to initiate a reaction (activation energ..

Global warming has already occurred and will continue to do so. Evaporation will increase as climate warms and there will be an increase in average global precipitation. Local climate conditions are likely to change depending on the modifications of local rainfall patterns. The quality a..

Every substance possesses a definite quantity of energy, under a given set of factors such as chemical nature of the substance, temperature and pressure. The total energy contained in a system or substance is called its internal energy or intrinsic energy. It is represented by the s..

Environment of earth includes the whole of atmosphere, hydrosphere as related to biosphere. Therefore, environment includes nature, composition of air, characters of hydrological parameters, sunshine, air pressure, temperature, water resources - their storage and flow and all other physical paramet..

The rainfall patterns in the world are governed by differential heating of air layers over different latitudes. Differential heating of air is the main reason for different convectional air current movement from one part of globe to other. The rainfall is associated with these convectional current..

Water can be acidified with a small quantity of sulphuric acid and taken in an electrolytic cell. When a direct current is passed through the water, it it undergoes electrolytic decomposition, to yield hydrogen and oxygen. If an electric current is passed through molten lead bromide, it d..

Internal Energy and Change in Internal Energy - Since chemical changes are always accompanied by energy changes, it indicates that reactants and products must be having certain amounts of energy. A fixed quantity of any substance is associated with a definite..

The cyclic changes in the ovary and uterus are under the control of estrogen and progesterone hormones whose secretion is under the control of gonadotropic hormones secreted by anterior pituitar..
