If a bimetallic strip is heated, it will

Bend towards the metal with lower linear thermal expansion coefficient

Bend towards the metal with higher linear thermal expansion coefficient

Not bend at all

None

Solution

A bimetallic strip consists of two metal strips fastened together. Metals are chosen that expand at different rates when the strips get hot. When one strip gets longer than the other, the combination has to bend. These strips are often used in thermostats in houses to control the house temperature. When the strip is cold, it bends one way, and as it gets hotter it bends the other way.
