Excerpt from book: HEAT Heat—Diamagnetic Force: While we do not know what heat actually is, we can best study it as having quantity and conditions in the same way as we deal ... more »with electricity by amperes and volts. Heat, as distinguished from temperature, may be said to be that which produces a negative, repulsive or diamagnetic force between the atoms tending to produce expansion or tending to overcome or reduce the positive force of attraction and cohesion. Temperature indicates the condition or intensity of the negative stress between the atoms and indicates the condition under which heat will pass from one body to another, but does not indicate the number of units of diamagnetic energy present. Temperature indicates the frequency of the vibration induced by the transfer of diamagnetic force from one body to another. No two forms of matter have the same specific heat, because no two forms of matter have a force of atomic attraction of the same intensity. Unit of Heat—Unit of Energy: The heat unit as now defined, viz.:—"The amount of heat necessary to raise one pound of water from 499 F. to 500 F. and having a work value equivalent of 774 ft. lbs." —though definite in itself, does not seem to be clearly understood in some respects. The definition states quantity and condition without differentiating between them. "One unit of heat" defines a definite quantity which has no work value whatever as no condition is stated, and may be characterized as the diamagnetic force produced in one unit of matter, but "One unit of heat" developed at the heat density or diamagnetic stress equivalent to 500 F. temperature in water, has a work equivalent of about 774 ft. lbs., just as one ampere of current has no work value, but one ampere of currentat 500 volts pressure has an established work value...« less
