WebJan 1, 2013 · When a solid is exposed in a closed space to a gas at pressure p, the weight of the solid typically increases and the pressure of the gas decreases: the gas is adsorbed by the solid. After a time, the pressure p does not change any more and correspondingly the weight ceases to increase any further: a dynamic equilibrium is reached. WebNov 17, 2024 · In fact, under such circumstances, gas phase molecules actually collide mainly with the other gas molecules present in the gas layer at the solid surface. … WebThere is no lateral interaction between the adsorbed molecules, meaning that gas molecules adsorbed close to one another don’t cause any alteration to each other. The adsorption is localized, i.e. the adsorbed molecule stays on the surface until it is desorbed. Only a single layer of molecules is formed. potatis synonym
