CARBIDES
All the various compounds of carbon with metals or other more electropositive elements are termed as carbides. True Carbides have the ion C4- (e.g. Al4C3). The properties of carbides resembles to those of salts. On hydrolysis they give methane and thus, were formerly called methanides. Dicarbides are compounds containing the ion C2-, these are also […]
SEMICONDUCTORSCONDUCTORS
A conductor is a substance that can conduct electricity or heat through it. In other words, we can say that a conductor is a substance that has a very high electrical or thermal conductivity (a measure of a substance to conduct heat or electricity). Conductors are usually […]
TRANSFER OF HEAT
The flow of heat from one body to another or from one place to another is called the transference of heat. Basically, there are three modes of transfer of heat conduction, convection and radiation.
THERMAL CONDUCTION
This is the slowest mode of heat transmission, where the energy is transferred from the hotter end to the […]
