Question:
An external pressure $\mathrm{P}$ is applied on a cube at $0^{\circ} \mathrm{C}$ so that it is equally compressed from all sides. $\mathrm{K}$ is the bulk modulus of the material of the cube and $\alpha$ is its coefficient of linear expansion. Suppose we want to bring the cube to its original size by heating. The temperature should be raised by:
$\frac{3 \alpha}{P K}$
$3 P K \alpha$
$\frac{P}{3 \alpha K}$
$\frac{P}{\alpha K}$
