...— The Doctrine of Latent Heat. THE Doctrine of Latent H«at is this : that in the change of a body from the solid to the liquid, or from the liquid to the aerial form, heat, is communicated to the body which is not indicated by the thermometer ; or, as it...

...applied to designate the heat •which is absorbed by bodies when they undergo a change of aggregation from the solid to the liquid, or from the liquid to the gaseous state. Thus, the heat which is required to convert ice, at a temperature of 32°, into water of the...

...caloric, which then becomes latent or insensible. And as heat is always absorbed in the passage of a body from the solid to the liquid, or from the liquid to the gaseous state, and again given out in the converse operation, the caloric thus taken up is either the actual...

...converted into a solid mass, so as to be handled and broken in pieces. 138. Whenever any substance passes from the solid to the liquid or from the liquid to the aeriform or gaseous state, caloric is absorbed and rendered latent or insensible ; and whenever a substance...

...former density, or is expanded three times. LATENT HEAT. If matter undergoes an important change, as from the solid to the liquid, or from the liquid to the gaseous state, it absorbs 'heat which is not measurable by the thermometer. In .matter which is condensed,...

...cold. QUANTITY OF HEAT IN BODIES. 59. Latent heat is observed, when bodies are changing their form from the solid to the liquid, or from the liquid to the aeriform state. But another equally remarkable phenomenon of heat is observed, in the amount necessary...

...observation. Latent heat always comes into play when a body changes its state of aggregation; when it passes from the solid to the liquid, or from the liquid to the vaporous or gaseous condition. While the case of water is still fresh in our minds, let us take it...

...explained that in all changes in the state of aggregation of bodies heat becomes latent or sensible. If a body passes from the solid to the liquid, or from the liquid to the gaseous state, heat becomes latent; in the inverse process an equal amount of heat becomes sensible. Black...

...in distinction from sensible heat; the portion of heat which disappears when a body changes its form from the solid to the liquid, or from the liquid to the aeriform state. LATEK, Id-ter, a. comparative degree of late. Posterior ; subsequent. LATERAL, laf-er-al,...
