With increase in the solute concentration, the specific heat of aqueous solutions _____________________?
Correct answer: B. Decreases
- A. Increases
- B. Decreases
- C. Remains unchanged
- D. Either A. or B.; depends on the type of solution
Explanation
Dissolved solutes commonly have lower specific heat than water, so increasing concentration usually lowers the specific heat of an aqueous solution. This is the standard engineering approximation for ordinary aqueous solutions.
