Question

191.Coefficients of cubical expansion of a metal cube is "gamma".Increase in temperature for which the volume of the cube Increases by 5% is

Answer 1

$$\begin{gathered} Formulaforcubicalexpansionis, \\ V=V_0\left(1+\gamma ∆T\right) \\ OR∆T=\frac{\left(V-V_0\right)}{V\gamma }=\frac{∆V}{V\gamma }=\frac{5}{100\gamma }. \\ Thereforetheincreaseintemperatureis0.05/\gamma . \end{gathered}$$
