1. The problem statement, all variables and given/known data I only know volumetric expansion and linear expansion which require the coefficient constants that are not given in the problem. I also read somewhere that the mass remains constant during thermal expansion or is this false? The problem is attached pls take a look at it. 2. Relevant equations delta V=BVi Dleta T 3. The attempt at a solution I tried finding the total energy but could not do anything after that.
