Answer 1

Answer:

B) Bend towards M2

A bimetallic strip is made of metals m1 and m2 on cooling through the same temperature, M1 contrast more than M2 when the strip is heated it will. Because M1 contracts more than M2 on cooling, M1 will also expand more than M2 on heating. the strip will bend towards M2.
