Answer
Silver and brass have coefficients of thermal expansion which are very similar. Therefore, the strip would not bend very much as the temperature of the strip increased. Silver and brass would not be a good choice of metals for a bimetallic strip.
Work Step by Step
A bimetallic strip works best when the two materials have very different coefficients of thermal expansion. As the temperature increases, one material changes length significantly more than the other material , which causes the strip to bend.
However, silver and brass have coefficients of thermal expansion which are very similar. Therefore, the strip would not bend very much as the temperature of the strip increased. Silver and brass would not be a good choice of metals for a bimetallic strip.
