phase-transition heat
81Critical exponent — Critical exponents describe the behaviour of physical quantities near continuous phase transitions. It is believed, though not proven, that they are universal, i.e. they do not depend on the details of the physical system, but only on the… …
82Point de fusion — Un panneau routier québécois rappelle le point de fusion de l eau à 0 °C Le point de fusion ou la température de fusion d un corps représente la température à une pression donnée, à laquelle un élément pur ou un composé chimique passe de l… …
83Thermal conduction — In heat transfer, conduction (or heat conduction) is a mode of transfer of energy within and between bodies of matter, due to a temperature gradient. Conduction means collisional and diffusive transfer of kinetic energy of particles of ponderable …
84Quark–gluon plasma — A QGP is formed at the collision point of two relativistically accelerated gold ions in the center of the STAR detector at the relativistic heavy ion collider at the Brookhaven national laboratory. A quark–gluon plasma …

86Steel — For other uses, see Steel (disambiguation). The steel cable of a colliery winding tower …
87Condensation — For other uses, see Condensation (disambiguation). Water vapour condenses into a liquid after making contact with the surface of a cold bottle …
88Plutonium — (pronEng|pluːˈtoʊniəm, symbol Pu, atomic number 94) is a rare radioactive, metallic chemical element. The most significant isotope of plutonium is 239Pu, with a half life of 24,100 years; this isotope is fissile and is used in most modern nuclear …
89Ringwoodite — is a high pressure polymorph of olivine, and it is stable at high temperatures and pressures like those in the Earth s mantle near 600 km depth. This mineral was first identified in the Tenham Meteorites in 1969, and it is inferred to be present… …
90Melting-point depression — This article deals with melting/freezing point depression due to very small particle size. For depression due to the mixture of another compound, see freezing point depression. Melting point depression is a term referring to the phenomenon of… …
