Answer #1

Salicylic acid contains two functional groups that are COOH and OH group being polar these are soluble in water but solubility is low because of intra molecular hydrogen bonding between the salicylic acid molecules apart from them it contains aromatic ring also which is no polar and hence less soluble. When temperature increases interaction between the molecules itself decrease and interactions with water increases . Hence solubility increases.

Hope this helps you.
