Excerpt from Chemistry From the Industrial StandpointAnother important thing to note is that ice floats on water. This, naturally, is because it is lighter than the water. So that the pound Of ice takes up more room than the pound of water it becomes on melting. This accounts for the bursting of water-pipes during a severe frost; the water on changing to ice requires more room and can only get it by splitting the pipe; of course, this is not noticed until the thaw, as the ice does not run out.Water, however, is almost solitary in ex panding when it becomes solid; most liquids contract, and the solid is heavier than the liquid, and thus Sinks in it. Type metal behaves like water when cast, and expands to give a sharp edge to the letters in the type; castings from most metals have to be made somewhat larger than required and machined when cold if a clean surface is required.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
