Answer to Question #237370 in Physical Chemistry for Garry

Question

What is the effect of increase temperature(heat)on the solubility of most solid substances when dissolved in water....

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.
