A bimetal made of copper and iron strips...

A bimetal made of copper and iron strips welded together is straight at room temperature. It is held vertically with iron strip towards left and copper strip towards right. If this bimetal is heated, it will

A

remain straight

B

bend towards right

C

bend towards left

D

bend forward

Text Solution

Verified by Experts

The correct Answer is:
c
Since `alpha_("copper")gt alpha_("iron")`, the bimetal will bend towards left (d) bend forward
