Answer to Question #291431 in Molecular Physics | Thermodynamics for xoxo

Question

caculate the linear expansivity of brass of length 120m, that assume a new length of 120.05m when headed through a temperature of 100

Answer 1

*Assuming the temperature change is 100°C.

$$\alpha=\dfrac{L-L_0}{L_0\Delta T}=4.167·10^{-16}\text{ 1/K}.$$
