Answer

Aluminum will be on the outside of the curve.

Work Step by Step

According to table 31-1, the expansion coefficient of aluminum is larger than that of iron. This means that when 2 joined straight strips of equal length are heated, the aluminum will become longer than the iron. The bimetallic strip bends in such a way that the longer strip is on the outside of the curve.
