Final answer:
Increasing the temperature generally causes the solubility of solids to increase while the solubility of gases decreases. The exact effect on solids can vary, with some showing dramatic increases and others only slight changes or even decreases in solubility.
Step-by-step explanation:
Based on the information provided in the solubility graphs, the effect of increasing the temperature on the solubility of substances can generally be stated as follows: for most solid substances, solubility increases with temperature. This can be seen in the upward trend of solubility curves on a graph that plots solubility against temperature.
However, the exact relationship between temperature and solubility can vary among different substances. For example, solubility may increase dramatically, change only slightly, or even decrease with an increase in temperature, depending on the substance in question.
For gases, the situation is different; the solubility of gases typically decreases as the temperature increases. This is because thermal energy overcomes the attractive forces between the gas molecules and the solvent, leading to lower solubility at higher temperatures.
