CBSE Class 8 Science Chapter 15 Some Natural Phenomena An earthquake is sudden shaking or trembling of surface of earth, occuring due to movement of hot fluid in the Earth’s crust. Earthquake last for very short time. In general, earthquakes are occurring all the time everywhere on the earth but they are not noticed. There […]

Redox Reaction

CBSE Class 11 Chemistry Chapter 8 Redox Reactions Occurance of reduction and oxidation process simultaneously with the chemical reaction is called redox reaction. Various phenomena like rusting of iron, browning of fruits, process of respiration, photosynthesis are result of redox reaction . However, redox reactions are mainly used in pharmaceuticals, industrial, metallurgical and in agricultural […]

CBSE Class 8 Science Chapter 1 Crop Production and Management In this article we will talk about what is irrigation and what are its different methods. Seeds in crop field germinates only if they get sufficient amount of water. Moreover, plants also need water for growth and development of flowers, fruits and seeds. Water is […]


CBSE Class 11 Chemistry Chapter 4 Chemical bonding and molecular structure Concept of hybridization was first introduced by Pauling. He explained shapes of polyatomic molecules. He found that, atomic orbital combine to form new set of equivalent orbitals known as hybrid orbitals. However, these hybrid orbitals are used for forming bond. This phenomena was called […]
