A strip of copper metal is riveted to a strip of aluminum. the two metals are then heated. the coefficient of linear expansion of aluminum is greater than that of copper. what happens?

We can base this on the equation of thermal expansion.

ΔL = L₀αΔT
where
ΔL is the expansion of length upon heating
L₀ is the initial length
α is the coefficient of linear expansion
ΔT is the temperature difference

So, if α for Aluminum is greater than α for Copper, then after heating, aluminum would be longer than copper.
