Abstract
THE heat of wetting of dry standard cellulose in water was measured at temperatures between 0° C. and 40° C. The cellulose and the experimental technique were those described previously1. The heat of wetting decreases with the rise of temperature as shown by the following values, which represent the means of several experimental results at each temperature: The decrease appears to be linear in the range tested, and amounts to about 0.042 cal./degree/gm. cellulose.
