Page 166 - The total energy of any material system is a quantity which can neither be increased nor diminished by any action between the parts of the system, though it may be transformed into any of the forms of which energy is susceptible.
Page 60 - The copper oxide is employed in the form of a compressed slab, which, with its connecting copper support, serves also as the negative plate.
Page 166 - In fact the doctrine of the Conservation of Energy is the one generalized statement which is found to be consistent with fact, not in one physical science only, but in all. When once apprehended it furnishes to the physical inquirer a principle on which he may hang every known law relating to physical actions, and by which he may be put in the way to discover the relations of such actions in new branches of science.

Page 169 - If we take as the unit of heat the heat required to raise one gramme of water from 0 C. to 1 C., and if t be measured in seconds, then H = 0-239 114.
Page 1 - No. 1, next page.) We will have frequent cause to refer to this table later, but as we will proceed from the ground up, we will now start in and describe the different batteries. An electric battery, or cell, as a single element is called, is a device for the conversion of the potential energy of chemical separation into the energy of an electric current. Thus the metal zinc on which sulphuric acid acts chemically represents energy of chemical separation in the potential form. If now the zinc is...
Page 168 - The unit of work is the erg. It is the work done by a dyne in producing a displacement of one centimetre in the direction of the force.
