Question

Identify the incorrect option from the following.


  1. Point 3
  2. All the mentioned points are correct.

  3. Point 1

  4. Point 2


Solution

The correct option is A Point 3

All the other points mentioned are correct except this. It should be: "Changes that can be undone are reversible change while the changes that can't be undone are irreversible change.”

Evaporation of water to become water vapour is a reversible change as it can be condensed back to water whereas baking bread is irreversible change as baked bread can't be unbaked.

Hence the correct summary will be as follows:

Point 1: Changes are the differences in the state of affairs.

Point 2: Change can be grouped into reversible and irreversible change.

Point 3: Change that can be undone is reversible change and change that can't be undone is irreversible change.

Point 4: There are many ways in which change can be brought.

For e.g. Heating, cooling etc.
