Since Haber's process proceeds with a decrease in volume, it is favored by high pressure. In actual practice, a pressure of 200 - 900 atmospheres is employe..

Metals have high tensile strength. Metals can resist stretching without breaking. A strong electrostatic attraction between the positively charged kernels and the mobile electrons surrounding them is the reason for tensile strengt..

In this process, coal is heated in the absence of air to about 1273 - 1473 K. The major products of high temperature pyrolysis are, Coal..

Ionic compounds have high melting and boiling points. A large amount of energy is required to break the crystal lattice, because the ions are held together by strong electrostatic forces of attraction. The variation in melting point depends upon the charges on the ions and ionic radii. T..

The molecule should contain an atom of high electronegativity such as F, O or N bonded to hydrogen atom. The common examples are H 2 O and NH 3..

It possesses excellent electrical insulating character and hence its major use in making electrical goods. Used to make combs, fountain pen barrels, gramophone records, electric goods, formica table tops. Sulphonated bakelites are used as ion exchange resi..
