The heat absorbed from the hot body will be nearly 540 gram-calories, the latent heat of steam at this temperature.
Are there any instances in which the abstraction of latent heat will reduce the hulk of bodies?
Nor can we ascribe the appearances to the liberation of latent heat, in consequence of condensation of volume.
The latent heat of steam at 90 pounds gage pressure is 881 heat units.
The grease lessens the friction; and (by diminishing the friction) the latent heat is less disturbed.
This second quantity is called the latent heat of the steam at 100°.
The theory of latent heat ought also to explain the phenomena noticed when liquid water is changed into steam.
Because the latent heat of the water passes away from between its atoms into the air; the atoms, therefore, draw closer together.
Whenever this takes place the air is brought again under pressure; it is compressed, and its latent heat becomes again sensible.
If you press gas suddenly into a fluid, the latent heat of the gas is set free.
The quantity of heat absorbed or released by a substance undergoing a change of state, such as ice changing to liquid water or liquid water changing to ice, at constant temperature and pressure. The latent heat absorbed by air when water vapor condenses is ultimately the source of the power of thunderstorms and hurricanes. See also heat capacity.
The heat released or absorbed when matter undergoes a change of phase (see phases of matter). If the heat is given off during the change from a liquid to a solid, it is called heat of fusion. If it is given off during the change from a gas to a liquid, it is called heat of vaporization.
