Question

An external pressure P is applied on a cube at 0^oC so that it is equally compressed from all sides. 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:

${P \over {3\alpha K}}$

${P \over {\alpha K}}$

${3 \alpha \over {P K}}$

3PK$\alpha$
