Asquare plate has an area of 29.00 cm2 at 20.0 ? c. it will be used in a low temperature experiment at t = 10.0 k where it must have an area of 28.00 cm2. what area must be removed form the plate at 20.0 °c for it to have the correct area at 10.0 k? (the coefficient of linear expansion is 10 10-6(° c)-1 .)
