Read the following statements :

Step 1 : A few spoons of sugar are dissolved in water to prepare a concentrated sugar syrup.
Step 2 : The sugar syrup is heated on low flame till it caramelizes.

Choose the correct option.

  • A.Step 1 is a physical change and Step 2 is a chemical change
  • B.Step 1 is a chemical change and Step 2 is a physical change
  • C.Both Step 1 and Step 2 are physical changes
  • D.Both Step 1 and Step 2 are chemical changes

Answer: A

Step 1 is a physical change and Step 2 is a chemical change.

Dissolving sugar in water is a physical change: no new substance forms, and the sugar can be recovered by evaporating the water.

Caramelization is a chemical change: heating breaks down the sugar into new substances with a different colour, smell and taste, and the change cannot be reversed. That rules out the options calling both steps the same kind of change, and the option that reverses them.
