Abstract
An account is given of the various forces involved in the adsorption of gases and vapours at a solid surface. The heat evolved during such processes may be measured by means of a microcalorimeter such as that designed by Calvet, whose description and application is discussed in detail. The use of such a microcalorimeter in studying adsorption at coal surfaces is described where differences in the measured differential heats of adsorption may be attributed either to the residual mineral content of the coal and/or to oxidation by air during its pretreatment.
