Question

Why would you expect the solubility of most solids to increase as the temperature of the solvent increases?

A The solubility of most solids decreases as the temperature of the solvent increases.

B At elevated temperature, the solvent evaporates, increasing the concentration of the solution

C At elevated temperature, there is more kinetic energy available to break the intermolecular forcers and dissolve the solute.

D At elevated temperature, the concentration of the solvent decreases, this increases the solubility of the solute.

E The solubility of most solids increases as the temperature of the solvent decreases.

F None of the above, the solubility of most solids DECEASES as the temperature of the solvent increases.

Would the answer just be A?

Explanation / Answer

(C) At elevated temperature, there is more kinetic energy available to break the intermolecular forcers and dissolve the solute.

Imagine a solvent like water made of tiny dots, molecules. Heat is basically the vibration of molecules. Solutes (things that dissolve) like salt dissolve by spreading its molecules through the solvent until you can't see it anymore. The faster the dots of the solvent (water) vibrate, the faster the solute (salt) is broken apart because the solvent (water) touches the solute (salt) more.
