| Title | Unpublished paper, 'On the existence of multiple proportion in the quantities of heat, or equivalent alteration of internal space of bodies, caused by definite changes of state as produced by chemical combination or otherwise' by Thomas Woods |
| Creator | Woods; Thomas |
| Date | November 1855 |
| Description | Woods suggests after consideration of existing research into the subject that it is evident that specific volume of its combining equivalent is characteristic of matter. However, as every substance is composed of matter and space, or of particles with some distance between them, as is shown by expansion and contraction, whenever volume is altered there must be either an addition to or subtraction from the internal space of the body. This alteration of volume is evident in the case of bodies expanding or contracting by gain or loss of heat; but in chemical combination, where alteration of internal space must also take place, in chemical combination, Woods suggests, this alteration of internal space is not so plainly demonstrable.
