2. The coefficient of linear expansion of steel is 12 X 10° K'. What is the change in length of a 25-m steel bridge span when it undergoes a temperature of 40 K? 2. The
I thought that the coefficient of linear thermal expansion would be what is given already...please help. 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...
The coefficient of linear expansion of a mystery metal alloy is 1.20 x 10-5 K 1. At 20.0° C a rod made of this alloy has a length of 11.9200 m. The rod is cooled to -29.0° C. Calculate the change in length (AL) of the rod. Remember that a negative change in length means that the length decreases, and a positive change in length means that the length increases. (There must be three significant figures in your answer.) x...
A certain metal has a coefficient of linear expansion of 2.00 × 10-5 K-1. It has been kept in a laboratory oven at 325°C for a long time. It is now removed from the oven and placed in a freezer at -145°C. After it has reached freezer temperature, the percent change in its density during this process is closest to A) +2.90%. B) -2.90%. C) +2.74%. D) -2.74%. The anwser is A. I need an explanation

The Eiffel tower, which is made of steel (coefficient of linear expansion 13 x 10^-6/ degree C.), is 320 m high at 20(Degrees C). the change in height of the tower between the winter months when the average temperature is -20C and the summer months when the average temperature is 35C is ? a. 42 cm b. 35 cm c. 23cm d. 15 cm e. 11cm
In this solution, just trying to understand why the coefficient of thermal expansion of steel is multiplied by 3. I understand volume is cubic. Don't need answer. Thx The average coefficient of volume expansion for carbon tetrachloride is 5.81 ✕ 10−4 (°C)−1. If a 55.0-gal steel container is filled completely with carbon tetrachloride when the temperature is 10.0°C, how much will spill over when the temperature rises to 26.5°C? (Assume the coefficient of thermal expansion of steel is 11 ✕...
