Brass and iron will have same rate of linear expansion.
True
False
When two different metals are subjected to same rise of temperature, they experience different rate of linear expansion.
An iron rod and another of brass, both at 27∘C differ in length by 10−3m. The coefficient of linear expansion for iron is 1.1×10−5/∘C and for brass is 1.9×10−5/∘C. The temperature at which both these rods will have the same length is
