Please Help! Can not find the correct answers.
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 | ||
| Material B | ||
| Material C | ||

The table at the right includes a few coefficients of linear expansion for some materials. You need to design an emergency overheating alarm using one of these materials. In your design, at room temperature (23.0°C), a 8.01 cm long cylinder of the material will sit with one end against a wall and the other just barely touching a button. Once the heat causes the cylinder to lengthen by 0.0238 cm, the button will be activated, turning on the alarm. At...

1. The George Washington Bridge crosses the Hudson River between New York and New Jersey. The span of the steel bridge is about 1.70 km. What might be the difference between the maximum span and minimum span over the course of a year, if the temperature can vary from a low of −15.0°F in winter to a high of 106°F in summer? Expansion coefficient of steel is α = 12.0 × 10^−6 K^−1. 2. A 2.30 m length of copper...
