Show ;t of Treating Tfaler. Water is one of the hardest of all substances sub-stances to heat. This furnishes a good illustration of the law of the conservation conserva-tion nnd transformation of forces. To raise one pound of water one degree in a minute is required a heat which, if applied ap-plied to an engine, would raise 772 pounds of water or any other substance one foot high. To raise eighty-six pounds one degree ill a minute would be equivalent to raising eighty-six times 772 pounds to the height of one toot in a minute. Washington Post. |
