A cube made of a metal of linear expansivity \(\alpha\) is warmed through a temperature of \(t\). if the initial 'volume of the cube is \(V\), what is the increase in volume of the cube?
A. \(\alpha Vt / 3\) B. \(\alpha V t / 2\) C. \(\alpha\) Vt\)A D. \(2 aV t\) E. \(3 \alpha Vt\)
Correct Answer: E
Explanation
Volume Expansivity \(=\underline{ V _{2}- V _{1}}\) \begin{array} &\gamma Vt = V , \text { where }=3 \alpha \text { Hence } 3 \alpha Vt = V \\ &\Delta V =3 \alpha Vt \end{array}
