Showing two glass test tubes in a laboratory setting, each with a thermometer immersed in water. The first test tube is labeled 'Solubility of Solids' and contains sodium chloride crystals. (NaCl) dissolving in water. The thermometer in this tube shows a temperature of 80°C. The second test tube is labeled 'Solubility of Gases' and contains water with bubbles of carbon dioxide. (CO2) which are decreasing as the temperature increases. The thermometer in this tube also shows 80°C. Each tube has clear labels indicating the type of solubility it represents., and there are arrows indicating the decrease in bubbles in the case of gases and the increase in the dissolution of crystals in the case of solids.
