Not illustrated. 1872 Excerpt: ...Thus the latent heat of water is 143 units, which is greater than that of any other liquid. When the liquid passes back into the solid state again, its latent heat reappears as sensible heat. 269. Heat causes Liquids to boil.--Under the ordinary pressure, if water be raised to a temperature of 212, it begins to boil, and its temperature then remains the same until it is all converted into steam. The heat, then, which the water absorbs changes it from the liquid to the gaseous state. Other liquids can be made to boil, but at very different temperatures. Any given liquid, under the same circumstances, always boils at the same temperature. 270. Latent Heat of Gases.--If a thermometer be held in the steam just over boiling water, it will indicate a temperature of 212. Now, as water is receiving heat all the time it is boiling, this heat must be latent in the steam. The latent heat of different gases is found to vary greatly. The latent heat of steam and watery vapor is greater than that of any other gas or vapor, hydrogen alone excepted. 271. The State of a Body depends upon its Temperature.--When a solid is heated, its temperature rises till it reaches the melting-point, where it remains stationary until the solid is melted. It then rises again until it reaches the boiling-point, where it again remains stationary until the liquid is converted into a gas. When a gas is sufficiently cooled, it goes through the same changes in the reverse order. It is because different substances have very different boiling-points that they can exist in nature, some as solids, some as liquids, and some as gases. 272. The Boiling-Point of Water falls as the Pressure on its Surface diminishes.--Fill a flask two-thirds full of water, boil it for some time, cork it tightly, removing ...
