In general, the specific heats of aqueous solutions _____________ with increase in the concentration of the solute?
Correct answer: D. Decrease
- A. Increase
- B. None of these
- C. Remain unchanged
- D. Decrease
Explanation
Adding solute usually replaces some water, whose specific heat is relatively high, with solute having a different and generally lower heat capacity. Therefore, the specific heat of most aqueous solutions decreases as concentration increases.
