Compressibility
111Specific heat capacity — Specific heat capacity, also known simply as specific heat, is the measure of the heat energy required to increase the temperature of a unit quantity of a substance by a certain temperature interval. The term originated primarily through the work …

113Hawker Typhoon — Typhoon Typhoon Ib EK139 N Dirty Dora of 175 Sqn. being armed with 500 lb (227 kg) concrete practice bombs in late 1943 …
114Model aircraft — A die cast Boeing 747 400 model. Model aircraft are flying or non flying models of existing or imaginary aircraft using a variety of materials including plastic, diecast metal, polystyrene, balsa wood, foam and fibreglass. Flying designs range… …
115Beta carbon nitride — (β C3N4) is a material predicted to be harder than diamond. [ [http://www.nature.com/news/2000/000511/full/news000511 1.html Access : Crunchy filling : Nature News ] ] The material was first proposed in 1985 by Marvin Cohen and Amy Liu. Examining …
116Vorticity equation — The vorticity equation is an important prognostic equation in the atmospheric sciences. Vorticity is a vector, therefore, there are three components. The equation of vorticity (three components in the canonical form) describes the total… …
117Fermi liquid — is a generic term for a quantum mechanical liquid of fermions that arises under certain physical conditions when the temperature is sufficiently low. The interaction between the particles of the many body system does not need to be small (see e.g …

119Bulk modulus — Incompressibility redirects here. For the topic in fluid dynamics, see Compressibility. Illustration of uniform compression The bulk modulus (K) of a substance measures the substance s resistance to uniform compression. It is defined as the… …
120Equivalent airspeed — (EAS) is the airspeed at sea level which represents the same dynamic pressure as that flying at the true airspeed (TAS) at altitude. It is useful for predicting aircraft handling, aerodynamic loads, stalling etc.EAS = TAS imes sqrt{frac{actual… …
