19. 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 β and the coefficient of volume expansion is α

(a)  P/( αβ )                                       (b)  (Pα) / β

(c)  (Pβ) /  α                                      (d)  (αβ) / P

Answer-a
