Question #175185

A metal of length 15.01m is heated until its temperature rises by 600C. If its new length is 15.05, calculate its linear expansivity

Expert's answer

The linear expansivity is

"\\alpha=\\frac{L_2-L_1}{L_1\\Delta T}=\\frac{15.05-15.01}{15.01\u00b7600}=4.44\u00b710^{-6}\\text{ K}^{-1}."
