"Bulk modulus is a modulus associated with a volume strain, when a volume is compressed. The formula for bulk modulus is bulk modulus = - ( pressure applied / fractional change in volume). Bulk modulu ...
"Boiling is the transition of a substance from the liquid to gaseous state of matter. When a liquid boils, its vapor pressure equals the atmospheric pressure. At high altitudes, liquids boil at a much ...

"Orbital diagrams are pictorial descriptions of the electrons in an atom. Three rules are useful in forming orbital diagrams. According to the Auf Bau Principle, each electron occupies the lowest ener ...
"Ohm's law defines a concrete relationship between potential difference and current flow. This relationship is satisfied by all ohmic materials according to the equation potential difference = - curre ...
