adj. Of or relating to carbon.

adj. Of, pertaining to, or obtained from, carbon.

Pertaining to carbon, or obtained from it.

An engine which is moved by the expansive force of condensed carbonic acid.

a substance (CO) obtained by allowing carbonic acid to pass over red-hot fragments of charcoal, contained in a tube of iron and porcelain, and also by several other processes. It is a colorless, inodorous gas, a little lighter than air, has neither acid nor alkaline properties, is very poisonous, and burns with a pale-lavender flame. This substance is produced when a coal-fire burns with a smokeless flame, and the pale-lavender flame produced by its combustion may often be observed playing over such a fire.

adj. relating to or consisting of or yielding carbon

"All limestones contain a great deal of this gas which issues from the candle, and which we call carbonic acid."
