Assertion (A): When a Bimetallic strip made up of brass and iron is heated then brass lies on the convex side.
Reason (R): Due to lower value of coefficient of linear expansion, brass acquires convex shape.

View answer and explanation

Correct option: C

If (A) is true but (R) is false

Option C (If (A) is true but (R) is false) is correct because brass has a higher coefficient of linear expansion than iron, causing it to lie on the convex side when heated.
