Not illustrated. 1871 edition. Excerpt: ... from the solid to the gaseous state; but those questions of chemical force do not lie directly in our simple course; and, as the specific heats have been found by actual experiment most carefully conducted, we accept and use them with the same assurance of approximate exactness as when employing the 14,000 and 4,000 units of heat in combustion. 346. We will now ascertain how far the 1,512 units, which we have already found lost or deficient in the raising of the peroxide oxygen to the gaseous state, is covered by the gain in temperature produced by condensation: and, in estimating, will treat the carbon and the oxygen of the carbonic oxide separately, but will employ for both the specific heat of the oxide state; then treat the oxygen of the ironstone with its own specific heat, and will use as a divisor the specific heat product belonging to their ultimate state as carbonic acid, when the ironstone oxygen has been received into combination; and will thereby get the number of units or degrees of heat that appear in the carbonic acid. 347. Owing to the difference in specific heat, less heat is required in the acid state to raise to a given temperature than is necessary in the oxide state, so that 7,000 apparent heat in case (1), will raise the same weight in case (2) to 8,515.
