Question

Now the friends use data obtained in the simulation to identify materials A-E. They calculate and record the value of α for each material and use the table below to identify it. (Hint: The simulation rounds some of the data to two-digit accuracy, so calculate all coefficients of linear thermal expansion using AT 50.) Material Steel Copper Brass and BronzeAluminum Lead a ((°C)1) 11 x 10-6 17 x 10-6 19 x 10-6 24 x 10-629 x 10-6 For each material, enter the value of the coefficient of linear thermal expansion, along with the name of the material Name of material 1.1e-5 Material steel Your response differs from the correct answer by more than 10% Double check your calculations 1.7e-5 Material copper Your response differs from the correct answer by more than 10% Double check your calculations 1.9e-5 Material brass Your response differs from the correct answer by more than 10% Double check your calculations 2.4e-5 Material aluminum Your response differs from the correct answer by more than 10% Double check your calculations Material 2.9e-5 lead Your response differs from the correct answer by more than 100%

I thought that the coefficient of linear thermal expansion would be what is given already...please help.
