1. The problem statement, all variables and given/known data A hole in an aluminum plate has a diameter of 1.179 cm at 22.00 degrees Celsius. Part A asks for the diameter of the hole at 199 degrees Celsius.? Part B asks for the temperature of the hole when its diameter is 1.177 cm? 2. Relevant equations ∆L = alpha L(0) ∆T 3. The attempt at a solution I got the answer for Part A. Here's what I did so far for Part B: I manipulated the equation as follows: ∆L/alpha*L(0) + Temp (initial) = Temp (final) And I used the difference between 1.177 and 1.179 cm for ∆L, used 1.179 for L(0) and the 22 degrees C for the initial temperature. Is this method correct?
