The pressure applied from all directions on a cube is P. How much its temperature should be raised to maintain the original volume ? The volume elasticity of the cube is \[\beta \] and the coefficient of volume expansion is \[\alpha \]

• A.    \[\frac{P}{\alpha \beta }\]     
• B.    \[\frac{P\alpha }{\beta }\]     
• C.           \[\frac{P\beta }{\alpha }\]      
• D.    \[\frac{\alpha \beta }{P}\]
