Question

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 $α$ . The metal sheet is heated uniformly, by a small temperature $Δ T$ , so that its new temperature is $T + Δ T$ . Calculate the increase in the volume of the metal box.

Options:

Answer:

B

Solution:

$Δ V = V γ Δ T$

$Δ V = 3 a^{3} α Δ T$
