Answer: heating of sugar is odd one out
Explanation: all the other processes mentioned are physical changes like tearing of paper, evaporation, preparing salt solution.
Heating of sugar is a chemical change since common sugar which is sucrose is made up of two glucose molecules and when you heat sugar the two molecules of glucose breakdown and leaves you with only glucose. This is not a physical process as we cannot get sucrose back by cooling the heated sugar.
