Thermodynamic Equilibrium

A system is said to be in the state of Thermodynamic equilibrium, if the microscopic variables describing the thermodynamic state of the system do not change with time. We consider a gas inside a closed rigid container completely insulated from the surroundings. If the pressure, volume, temperature, mass and composition of gas do not change […]

Thermodynamics is a branch of science that deals with the concept of heat and temperature and the inter-conversion of heat and other forms of energy. It mainly deal with the transformation of heat into mechanical work and vice versa. (I) Thermodynamic System An assembly of a very large number of particles having a certain value

Heat is the form of energy which flows from hotter body to colder body by virtue of temperature difference. The process of transfer of heat is a non-mechanical process i.e there is no mechanical work involve in the process of heat transfer. The amount of heat is measured in joule (SI unit) and other widely

Temperature is the measure of degree of hotness or coldness of a body. The measurement of temperature of a body is a relative measure. We can consider three body with temperature T₁, T₂ and T₃, where T₁>T₂>T₃ then the body T₁ is called hotter one with respect to another one which is known as colder

Scientific Names of The Most Common Animals, Birds And Plants

Common Animals, Birds and Plants Names With Their Scientific Names Scientific names, also known as binomial nomenclature, are a standardized system used to classify and identify living organisms based on their shared characteristics. These names consist of two parts, the genus and species, and are written in Latin or derived from Latin words. The use

Elastic Behaviour Of Solids

The atoms in a solid are held together by interatomic or intermolecular forces. These forces keep solid in a stable equilibrium position. When a solid is deformed, the atoms or molecules are displaced from their equilibrium positions. Thus, deformation causes change in interatomic or intermolecular distances. On removing deforming forces, the inter atomic forces tend

Elastic and Plastic Body

Elastic Body A body that returns to its original shape and size on the removal of the deforming force (when deform within elastic limit) is called an elastic body. Example: Quartz fibre, Ivory ball and phospher bronze etc. Elasticity The property of matter by virtue of which it regains its original shape and size, when
