For example in water, why is solubility of compound less in ice water? Can anybody explain the difference between the nature of bonding in hot and cold water?
Increased temperature usually increases the solubility of solids in liquids. To understand why, we need to return to the Second Law of Thermodynamics. Increased temperature means a greater average velocity for the particles. This allows them to move from one position to another more easily. The greater freedom of movement allows the system to change its state more easily, and in keeping with the Second Law, it changes to the most probable state available, that is, the most dispersed state of which it is capable. Solids are condensed systems, so the dissolving of a solid usually leads to increased dispersal of the system. Therefore, although there are exceptions, an increase in temperature generally leads to an increase in a solid’s solubility. You can find more detials on this link:
