Question

On heating a bimetallic strip made from brass and iron, the brass strip expands more. $({\alpha }_{brass}>{\alpha }_{iron})$

• A. True
• B. False

Answer 1

The correct option is A

True

On heating a bimetallic strip made from brass and iron, both the strips will expand. But, the brass strip will expand more than the iron stip because the linear coefficient of thermal expansion for brass is greater than linear coefficient of thermal expansion for iron.
