Super Invar TM, an alloy of iron and nickel, is a strong material with a very low coefficient of linear expansion [0.2 x 10-6 (Co)-1]. A 2.0-m-long tabletop made of this alloy is used for sensitive laser measurements where extremely high tolerances are required. How much will this table expand along its length if the temperature increases 5.0 Co? Compare to tabletops made of steel.
