vaporization coefficient

vaporization coefficient

[‚vā·pə·rə′zā·shən ‚kō·ə·fish·ənt] (thermodynamics) The ratio of the rate of vaporization of a solid or liquid at a given temperature and corresponding vapor pressure to the rate of vaporization that would be necessary to produce the same vapor pressure at this temperature if every vapor molecule striking the solid or liquid were absorbed there.
