Liquefaction of Gases
Trending!
Liquefaction of Gases – Critical Phenomenon
A gas can be liquefied by lowering the temperature and increasing the pressure. At lower temperature, the gas molecules lose kinetic energy. The slow moving molecules then aggregate due to intermolecular attractions between them and are converted into liquid. The increase of pressure - The gas molecules come closer by compression and coalesce to form the liquid.

Valence Bond theory (with hybridization)
Trending!
A view of chemical bonding in which bonds arise from the overlap of atomic orbitals on two atoms to give a bonding orbital of electrons localized between the bonded atoms. Basic Principle: A covalent bond forms when the orbitals of two atoms overlap and the overlap region, which is between the nuclei, is occupied by a pair of electrons.

Basic Electronics
Trending!
A normal P-N junction diode is usually fabricated by adjusting the P-type and N-type semiconductors on a single semiconductor crystal. The characteristics of a junction diode demonstrate that it is designed largely for operating in the forward direction. Applying a large amount of forward bias causes greater forward current with a small value of forward voltage.
