liquefaction   (lĭk'wə-fāk'shən)  Pronunciation Key 
  1. Chemistry The act or process of turning a gas into a liquid. Liquefaction is usually achieved by compression of vapors (provided the temperature of the gas is below the critical temperature), by refrigeration, or by adiabatic expansion.

  2. Geology The process by which sediment that is very wet starts to behave like a liquid. Liquefaction occurs because of the increased pore pressure and reduced effective stress between solid particles generated by the presence of liquid. It is often caused by severe shaking, especially that associated with earthquakes.

liquefaction

change of a solid into a liquid when heat is applied. In a pure crystalline solid, this process occurs at a fixed temperature called the melting point (q.v.); an impure solid generally melts over a range of temperatures below the melting point of the principal component. Amorphous (non-crystalline) substances such as glass or pitch melt by gradually decreasing in viscosity as temperature is raised, with no sharp transition from solid to liquid
