Defination- When some material cold below the certain temperature  (called critical temp.) then the resistance dropped to zero.this type of material are called superconductor and this phenomenona is called superconductivity What is a superconductor? Superconductors are materials that conduct electricity with...

Thermodynamic definations of thermodynamics Thermodynamics is a branch of science concerned with heat and temperature and their relation to energy and work. The behavior of these quantities is governed by the four laws of thermodynamics, irrespective of the composition or specific properties of the...

DEFINATION When a liquid or solid dielectric placed in an external electric field , it's​ atoms becomes electric dipole which provides field which is different than applied field.the total field at the atomic sites is called the internal field or local field.it is represented by Ei or EL        E(local...

Nano particles DEFINATION particles that have at least one dimension that measures 100 nanometers or less are called nano particles. The propertiesof many conventional materials change when formed from nanoparticles. This is typically because nanoparticles have a greater surface area per weight than...

 2 stroke engine Theory In this engine cycle is completed in two stroke of the piston or in one revolution of crankshaft . The preparatory stroke. In two stroke engine,insted of valve port are used for sunction and exhaust purpose. As the moving parts are less,mechanical efficiency is high but thermal efficiency...

Four stroke Engine Some important definition in engine 1)clearence volume - the volume between upper part of cylinder and tdc is called clearence volume 2)Stroke volume - the volume swept by the piston from BDC to TDC is called stroke volume.it is also known as swept volume. 3)Break...

Definition the state of matter in which materials are retain their boundaries without support, the atoms or molecules occupying fixed positions with respect to each other and unable to move freely. Types of solid:- 1.      Crystalline Solid :- Eg:- Metals And Non metals 2.      Amorphous...
