; place the thermometer in a flask of water (fig. 20),Apply heat to the flask, and note the tempera-ture at which the wax melts. Remove theflame, and again note the temperature whenit begins to solidify. The mean of these twotemperatures is the melting-point. Wax begins to melt at . 49° C.„ „… … Fig. 20. Latent Heat of Fusion.—It is evident, that a large amountof heat is necessary to melt a solid at the temperature of itsmelting-point, into a liquid at the same temperature ; this heatwas said to be latent, and was called latent heat. The termis misleading; the heat is no more latent than…
