{Latent heat} (Physics), that quantity of heat which disappears or becomes concealed in a body while producing some change in it other than rise of temperature, as fusion, evaporation, or expansion, the quantity being constant for each particular body and for each species of change; the amount of heat required to produce a change of phase.

{Latent period}. (a) (Med.) The regular time in which a disease is supposed to be existing without manifesting itself. (b) (Physiol.) One of the phases in a simple muscular contraction, in which invisible preparatory changes are taking place in the nerve and muscle. (c) (Biol.)
