Question

Imagine a cube with initial side length 'l' that undergoes thermal expansion due to a temperature increase $\Delta T$ . Which equation correctly represents the relationship between the change in volume $\Delta V$ and the coefficient of linear expansion $\alpha_l$ ?

A

$\Delta V = 3l^2 \alpha_l l \Delta T$

B

$\Delta V = 2l^2 \alpha_l l \Delta T$

C

$\Delta V = l^2 \alpha_l l \Delta T$

D

$\Delta V = 4l^2 \alpha_l l \Delta T$

Accepted Answer

$ \Delta V = 3l^2 \alpha_l l \Delta T $

Answer

$ \Delta V = 2l^2 \alpha_l l \Delta T $

Answer

$ \Delta V = l^2 \alpha_l l \Delta T $

Answer

$ \Delta V = 4l^2 \alpha_l l \Delta T $
