Statement B: Cooling can also bring about change.

Select the correct option about the given statements.

• A. Group A
• B. Group B
• C. Both A and B are correct.
• D. None of them are correct.

Answer 1

The correct option is C

Both A and B are correct.

When a metal is heated, it expands and when it is cooled, it contracts so heating and cooling both bring about a change. Heating leads to expansion and cooling leads to contraction. So both the statements are true.
