Concept:Temperature has opposite effects on the solubility of solids and gases in a liquid.
Explanation:For most solid solutes in a liquid, solubility increases as temperature increases.
Heat provides energy that helps break the solid particles apart and allows more solute to dissolve.
For gases, the opposite trend is observed.
Increasing temperature gives gas molecules more kinetic energy, causing them to escape from the liquid more easily.
So higher temperature decreases the solubility of a gas in a liquid.
Thus, the general effect of raising temperature is not the same for solids and gases.
Answer:Increasing temperature generally increases the solubility of a solid in a liquid but decreases the solubility of a gas in a liquid.
Correct option: B.
