This loss can increase until it involves the entire amount of the latent heat, when the matter returns to the liquid form. Vapor can then have various charges of heat energy. But, when under atmospheric conditions this vapor is reheated and its temperature gradually approaches that station we have designated as Vv it can slowly regain this lost energy as sensible heat in the gaseous state. Then at Vv, under this condition, it will once more be in possession of its full quota of heat energy, and it will again have driven off the last remnant of cohesion of the vaporous state. This energy of sensible heat acquired in the gaseous condition, it cannot lose without a change of temperature. Hence the product must now have reached the condition of a perfect gas, and under still higher temperatures will act as such. Then, as stated by Regnault, its specific heat will not vary with the temperature, for as described it must be possessed of its latent heat of vaporization. This condition is reached with bodies possessing low boilingpoints when held at laboratory temperature, because their particles hold heat energy in excess of their energy of cohesion and they cannot lose the same by contact with neighboring particles. At B P then, under suitable pressure, and at Vv, under atmospheric conditions we have material in such a state that all cohesion of the liquid and solid states are balanced by heat energy. At the station thus denned, we can place the zero condition, the origin of the perfect gas. When heated above this station all increase of energy must be heat energy. Hence we can distinguish this state as the But before reaching this station its sp?cific ...
