    • curing, hardening, set, solidification, solidifying - the process of becoming hard or solid by cooling or drying or crystallization
    • inactivation - the process of rendering inactive
    • ion exchange - a process in which ions are exchanged between a solution and an insoluble (usually resinous) solid; widely used in industrial processing
    • ionisation, ionization - the process of ionizing; the formation of ions by separating atoms or molecules or radicals or by adding or subtracting electrons from atoms by strong electric fields in a gas
    • leach, leaching - the process of leaching
    • magnetic induction, magnetisation, magnetization - the process that makes a substance magnetic (temporarily or permanently)
    • materialisation, materialization - the process of coming into being; becoming reality
    • nuclear reaction - (physics) a process that alters the energy or structure or composition of atomic nuclei
    • opacification - the process of becoming cloudy or opaque
    • oscillation - the process of oscillating between states
    • oxygenation - the process of providing or combining or treating with oxygen
    • pair creation, pair formation, pair production - the transformation of a gamma-ray photon into an electron and a positron when the photon passes close to an atomic nucleus
    • phase change, phase transition, physical change, state change - a change from one state (solid or liquid or gas) to another without a change in chemical composition
    • precession of the equinoxes - a slow westward shift of the equinoxes along the plane of the ecliptic caused by precession of the Earth's axis of rotation
    • release - a process that liberates or discharges something
    • saltation - (geology) the leaping movement of sand or soil particles as they are transported in a fluid medium over an uneven surface
    • scattering - the physical process in which particles are deflected haphazardly as a result of collisions
