A metal rod is 25.000cm long at 25.0 degrees Celsius. When heated to 102.0 degrees Celsius, it is 25.054 cm long. What is the coefficient of linear expansion for this metal?

    \[\large\alpha_L=\frac1L\frac{dL}{dT}\approx\frac1L\frac{\Delta L}{\Delta T}\]

    Well.. I think that's a bad reply. L is the Length.. dL/dT is rate of change of unit length per change in unit temp. alpha would be your coeffiecient.. 1/25cm * (25.054-25.0)/(102.0-25.0) You said Rod.. Hot Rod..
