METHOD FOR DETERMINING ADSORPTION HEAT AND WETTING HEAT OF A SURFACE AND A MEASURING CELL OF A CALORIMETER

摘要

A sample of a material is placed into a measuring cell of a calorimeter consisting of upper and the lower parts connected with each other by a movable detachable tight connection. The cell is equipped with two coaxially arranged tubes capable of independent connection to external devices. An outer tube is connected to the upper part of the cell and an inner tube is connected to the lower part of the cell via the movable detachable tight connection and is movable. At least once a contact of the sample with vapor of a liquid is provided and heat of adsorption is measured, then contact of the sample with the same or another liquid is provided and heat of wetting of the sample by the same or the other liquid is measured.
