Question:

(a) An aluminum measuring rod, which is correct at 5.0 °C, measures a certain distance as 88.42 cm at 35.0 °C. Determine the error in measuring the distance due to the expansion of the rod. 

(b) If this aluminum rod measures a length of steel as 88.42 cm at 35.0 °C, what is the correct length of the steel at 35 °C? The coefficient of linear expansion of that sample of aluminum is 22 × 10-6 °C-1.
