Question
If a bimetallic strip is heated, it will
Options
A.bend towards the metal with lower thermal expansion coefficient.
B.bend towards the metal with higher thermal expansion coefficient.
C.twist itself into helix.
D.have no bending.
Solution
In bimetallic strips the two metals have different thermal expansion coefficient. Hence on heating it bents towards the metal with lower thermal expansion coefficient.
