Part 6 of 6 - Analyze 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 ΔT = 50°.) Material Steel Copper Brass and Bronze Aluminum Lead 𝛼 ((°C)−1) 11 ✕ 10−6 17 ✕ 10−6 19 ✕ 10−6 24 ✕ 10−6 29 ✕ 10−6 For each material, enter the value of the coefficient of linear thermal expansion, along with the name of the material. 𝛼 ((°C)−1) Name of material Material A 24e-6 Correct: Your answer is correct. Aluminum Correct: Your answer is correct. Material B 19e-6 Correct: Your answer is correct. Brass and Bronze Correct: Your answer is correct. Material C 29.3e-6 Changed: Your submitted answer was incorrect. Your current answer has not been submitted. Your response differs from the correct answer by more than 10%. Double check your calculations. Lead Incorrect: Your answer is incorrect. Material D 17.3e-6 Incorrect: Your answer is incorrect. Your response differs from the correct answer by more than 10%. Double check your calculations. Copper Incorrect: Your answer is incorrect. Material E 11e-6 Correct: Your answer is correct. Steel Correct: Your answer is correct.

For Material C and Material D, the provided values and identifications were incorrect. Based on the process of elimination and the feedback indicating a difference of more than 10% from the correct value, the materials should be identified as follows:

Material C:
The materials already correctly identified are Aluminum ($24 \times 10^{-6}$), Brass and Bronze ($19 \times 10^{-6}$), and Steel ($11 \times 10^{-6}$). The remaining materials are Copper ($17 \times 10^{-6}$) and Lead ($29 \times 10^{-6}$).
The user's calculated value for Material C was $29.3 \times 10^{-6}$ and identified as Lead. However, the feedback stated this was incorrect and differed by more than 10%. If Material C were Lead ($29 \times 10^{-6}$), the difference would be only 1.03%, contradicting the feedback. Therefore, Material C must be Copper.
The correct coefficient of linear thermal expansion for Copper is $17 \times 10^{-6}$ ($^\circ$C)$^{-1}$.
$\alpha = \boxed{17 \times 10^{-6}\ (\text{°C})^{-1}}$
Name of material: $\boxed{\text{Copper}}$

Material D:
Since Material C is Copper, Material D must be Lead.
The correct coefficient of linear thermal expansion for Lead is $29 \times 10^{-6}$ ($^\circ$C)$^{-1}$.
$\alpha = \boxed{29 \times 10^{-6}\ (\text{°C})^{-1}}$
Name of material: $\boxed{\text{Lead}}$
