Feu synonyms

The only work he published was his Reflexions sur la puissance motrice du feu et sur les machines propres a developper cette puissance (Paris, 1824).

Regarding heat (matiere de feu or fluide igne) as a peculiar kind of imponderable matter, Lavoisier held that the three states of aggregation - solid, liquid and gas - were modes of matter, each depending on the amount of matiere de feu with which the ponderable substances concerned were interpenetrated and combined; and this view enabled him correctly to anticipate that gases would be reduced to liquids and solids by the influence of cold and pressure.
