Linear Expansivity and its Applications
 

Linear Expansivity and its Applications problem 9


There are two rods at a room temperature . The first is made of aluminium and is 60.0 cm long, the second is made of iron and is 60.2 cm long.

  • At what temperature will the rods be of the same length?

  • What is this length?


The linear expansivity of aluminium is and that of iron is .
