Question 7 (1 point) A metal rod 40.0000-cm long at 33 °C is heated to 60 °C. The length of the rod is then measured to be 40.125 cm. The coefficient of linear expansion of the metal is °C-1. (Round your answer to six decimal places) Your Answer: Answer
An unknown metal rod has an initial length of 39.82 ± 0.02 cm at 21.5 ± 0.2 oC. The rod is heated to a temperature of 97.8 ± 0.2 oC and the change in length recorded at various temperatures, as shown in the given table. Generate an accurate graph of the change in length as a function of the measured temperature. From the slope, determine the coefficient of linear expansion for the rod. From the intercept, determine the coefficient of...
When a metal rod is heated, not only its resistance but also its length and cross‐sectional area change. The relation R = ρL / A suggests that all three factors should be taken into account in measuring ρ at various temperatures. If the temperature changes by 1.10oC, what percentage changes in (a) L, (b) A, and (c) R occur for a copper conductor? The coefficient of linear expansion is 1.70 × 10-5 K-1. Coefficient of resistivity for copper is 4.30...
In the practice of linear expansion metal rod initially had a length of 600mm at a temperature of 21 ° C. was heated to 100 ° C and a length of 0610 mm therefore dilated, its coefficient of thermal linear expansion is: 12.8 X 10.6 mm / mm oC 10.8 X 10.6 mm / mm ° C-1 14.8 X 10.6 mm / mm ° C-1 16.8 X 10.6 mm / MMOC-1
