1. The problem statement, all variables and given/known data Some cookware has a stainless steel interior (alpha = 17.3 *10^- 6) and a copper bottom (alpha = 17.0 * 10^-6) for better heat distribution. Suppose an 8.0 in. pot of this construction is heated to 620 C on the stove. 2. Relevant equations Delta L = alpha* Lo * delta T 3. The attempt at a solution I used the definition of coefficient of linear expansion to find the change in diameter for both copper and stainless steel. For stainless steel I found 0.083 inches, and for copper I found 0.0812 inches. I don't know where I am supposed to go from here, this is a homework problem online, and neither of the above answers nor their difference is the correct answer. Please help!!
