If a bimetallic strip is heated, it will

A

bend towards the metal with lower themal expansion coefficient.

B

bend towards the metal with higher thermal expansion coefficient.

C

twist itself into helix.

D

have no bending.

Text Solution

Verified by Experts

The correct Answer is:
A
In bimetallic strips the two melts have different thermal expansion coefficient. Hence on heating it bents towards the metal with lower thermal expansion coefficient
