Excerpt from Cyclopedia of Engineering, Vol. 2 of 7: A General Reference Work on Steam Boilers, Pumps, Engines, and Turbines, Gas and Oil Engines, Automobiles, EtcSir Humphry Davy showed that two pieces of ice might be melted by rubbing them together. He thus proved that heat can be produced by the expenditure of work only. This leads to the important conclusion that heat must be a form of energy, Since it can be produced from energy, and (as we know in the case of the steam engine) can itself be converted into well-recognized forms of energy.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
