Abstract
IN a recent paper1, it has been shown that it is possible to study the adsorption of hydrogen and oxygen on a tungsten wire and to measure the heat evolved and the amount of gas adsorbed. Experiments have now been carried out with similar apparatus using nitrogen, and they have shown that, if less nitrogen than is sufficient to cover the bare wire is admitted, the whole of this nitrogen is rapidly adsorbed on the wire, that is, the residual pressure is negligible. The behaviour of nitrogen is thus similar to that of hydrogen. The adsorption of the whole charge shows definitely that the effects observed cannot be due to impurities of, for example, oxygen in the nitrogen. The experiments were carried out at room temperature.
