Question 30 of 126

Each side of a box made of metal sheet in cubic shape is $a$ at room temperature $T$ , the coefficient of linear expansion of the metal sheet is $\alpha$ . The metal sheet is heated uniformly, by a small temperature $\Delta T$ , so that its new temperature is $T+\Delta T$ . Calculate the increase in the volume of the metal box.

Show answer and solution

Answer: (B) $3{a}^{3}\alpha \Delta T$

\Delta V=V\gamma \Delta T

\Delta V=3{a}^{3}\alpha \Delta T
