Answer: Option C
Solution
Answer: Option C
Solution:
Fresh water cooled to zero degree Celsius and subjected to additional loss of heat energy normally will freeze. A mixture of fresh water and ice has an equilibrium temperature of zero degree Celsius. Adding heat to the mixture causes ice to melt whereas removing heat causes water to freeze. So, no change will happen.
