Question

how does heat affect the solubility of a substance in a liquid? ​

Answer 1

For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

Answer 2

Answer:

Heat increases the solubility as it causes an increase in the intermolecular space of the liquid.

Hence heat is directly proportional to the solubility of a substance
