A. increase with an increase in temperature
B. decrease with an increase in temperature
C. decrease with a decrease in temperature
D. not be affected by changes in temperature
Correct Answer:
Option A – increase with an increase in temperature
Explanation
For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperature allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.
