WebIn general, for relatively dilute solutions, the activity of a substance and its molar concentration is roughly equal. The activity of pure solids and liquids is always equal to 1 because, per unit volume, the concentration of a pure solid or liquid is always the same. For example, the activity of liquid water is 1, and the activity of 5 grams ...

WebA solid can be classified as a substance that is rigid with low intermolecular spacing and high intermolecular forces, that binds all molecules within together. Liquids, on the other hand, are less rigid and flow easily. They usually have properties that enable them to flow from higher areas to lower areas. WebSome patterns emerge when these values are compared. The entropies of gases are much larger than those of liquids, which are larger than those of solids (columns 1, 3, and 4). This can be predicted from equation (1): heat must be put into substances to convert them from solid to liquid or liquid to gas. Therefore, q and D S are both positive ... kofc membership records
