1.	An external pressure \[P\] is applied on a cube at \[0{}^\circ C\]so that it is equally compressed from all sides. K is the bulk modulus of the material of the cube and a 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
A.	\[\frac{3\alpha }{PK}\]
B.	\[3PK\alpha \]
C.	\[\frac{P}{3\alpha K}\]
D.	\[\frac{P}{\alpha K}\]
Answer» D. \[\frac{P}{\alpha K}\]
