principles governing the degradation of energy

Laws Governing Energy Transformations - The storage and expenditure of energy in an ecosystem is in accordance with the laws of thermodynamics (basic laws of thermodynamics). The first law of thermodynamics is the law of conservation of energy, which says tha..

A positively charged particle can be accelerated to high energy with the help of an oscillating electric field, by making it cross the same electric field time and again with the use of a strong magnetic fiel..

Energy is the capacity to do work. All living organisms require energy for carrying on their vital metabolic activities. The primary source of energy for living system is solar radiation. The radiant energy of sunlight cannot be utilised directly by all livi..

The Aufbau principle states that in the ground state of an atom, an electron enters the orbital of lowest energy first, and then the subsequent electrons are fed in the order of increasing energies into the orbitals. The relative energies of various orb..

When the blowing wind strikes across the blades of a windmill, it exerts a force on them due to which the blades of the windmill start rotating. This in turn rotates the shaft of the turbine and generates electricity. ..

Solar Cells - Solar cells are expensive and are used only when supplying electricity becomes difficult. Solar cells are the devices where solar energy is directly converted into electricity. Solar cells are used in spacecrafts, radios, television, refrigerators, buoys and other navigation..

Thus, the Pauli's exclusion principle may also be stated as "An orbital can have maximum of two electrons and these two must have opposite spin". The maximum number of electrons in each main energy level can be predicted by extending this principle. The tabular column ..

Semiconductors whose conductivity is more than insulators and less than metals are used in electronic devices. The conductivity of the semiconductors increase when light falls on it. Wafers of doped semiconductors are so arranged that when sunlight falls on the arrangement, potential differences ar..
