Sphe‐roid″al (?), a. [[Cf. F. sphéroïdal.]] Having the form of a spheroid. — Sphe‐roid″al‐ly, adv. Spheroidal state (Physics.), the state of a liquid, as water, when, on being thrown on a surface of highly heated metal, it rolls about in spheroidal drops or masses, at a temperature several degrees below ebullition, and without actual contact with the heated surface, — a phenomenon due to the repulsive force of heat, the intervention of a cushion of nonconducting vapor, and the cooling effect of evaporation.
