The Rate of a Chemical Reaction The rate of a chemical reaction can be defined as the amount of the reaction which occurs in unit time. The rate of a reaction is measured by choosing certain properties of the reaction which will indicate how far the reaction has gone, and whose magnitude can be observed … Read more

Kinetic theory of gases The kinetic theory describes a gas as a large number of submicroscopic particles (atoms or Molecules), all of which are in constant rapid motion that has randomness arising from their many collisions with each other and with the walls of the container. According to kinetic theory of gases, the molecules of … Read more
Motion Motion is a change in position of an object with respect to time. Motion is typically described in terms of displacement, distance, velocity, acceleration, time and speed. The branch of physics which deals with the study of motion of material objects is called mechanics. Mechanics is divided into following branches. (i) Statics : Statics … Read more
Orogenic or the mountain-forming movements act tangentially to the earth surface, as in Plate tectonics. Tensions produces fissures (since this type of force acts away from a point in two directions) and compression produces folds (because this type of force acts towards a point from two or more directions). In the Landforms so produced, … Read more
The Indian Plate is one of the major tectonic plates of Earth’s lithosphere. It is bounded by the Eurasian Plate to the north, the African Plate to the west, the Australian Plate to the southeast, and the Antarctic Plate to the south. The Indian Plate is a relatively young plate, having formed approximately 80 million … Read more
The Planetesimal Hypothesis of Chamberlin and Moulton is a theory about the formation of The Solar System. It states that the solar system formed from a cloud of gas and dust that collapsed under its own gravity. The cloud flattened into a disk, and the planets formed from the material in the disk. The hypothesis … Read more
The origin of the Earth is a topic of great interest to scientists and laypeople alike. There are many different theories about how the Earth formed, but the most widely accepted theory is that the Earth formed from the accretion of dust and gas in the solar nebula. This theory is supported by a number … Read more
