Answer:
A description that includes four of the following points:
- (A) (increase in temperature can) (linear) increase the solubility (1)
- (B) (increase in temperature (up to \(32^{\circ} \mathrm{C}\) ) can) (exponentially) increase the solubility and then decrease it (1)
- (C) (increase in temperature can have) a slight increase on the solubility (1)
- (D) (increase in temperature can) decrease the solubility (1)
- statement referring to different chemicals have different solubilities at different temperatures (1)
