. Thermionic emission is the phenomenon by which free electrons from surface of a metal are emitted when heated to a high temperature. Example 2:- What are Cathode rays? Give three properties of these rays. Suggested Answer:- Cathode rays are a beam of electrons emitted from a hot cathode. Properti..

Energy Level Diagram for Molecular Orbitals - The relative energies of molecular orbitals depend upon the following two factors: (i) the energies of the atomic orbitals combining to form molecular orbitals. (ii) the extent of overlapping between the atomic or..

The relative energies of molecular orbitals depend upon the following two factors: (i) the energies of the atomic orbitals combining to form molecular orbitals. (ii) the extent of overlapping between the atomic orbitals. The greater the overlap, the more the bonding orbital is l..

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..

Although matter circulates, energy cannot be reused indefinitely. Solar energy is converted by the photosynthetic producers (plants) into chemical energy in the form of plant carbohydrates. Herbivores consume the plant carbohydrates and so this chemical energy..

Valence band and the conduction band lies in the energy gap. According to the Bohr's theory, free electrons in an isolated atom have certain definite discrete amount of energy. If large number of atoms are brought close to one another to form a crystal, they begin to influence ..

Water stored in a reservoir is capable of rotating turbines, which are kept at a lower level i.e, water stored in a reservoir possesses energy..

The ionization energy of hydrogen is quite close to that of halogens. H : 1312 kJ mol - 1 , Cl : 1255 kJ mol - ..

. Here again some of the energy is released as heat. When primary consumers are eaten by secondary consumers, the same process is repeated at every step of the food chain. Here it must be remembered, that energy released as heat is considered as energy lost. We can thu..

Pyramid of Energy - "Pyramid of energy is a graphic representation of the amount of energy trapped per unit time and area in different trophic level of a food chain with producers forming the base and the top carnivores at the tip". Pyramid of Energy..
