Heat and Thermodynamics question

2017 · Shift 0 · Q58

JEE MainPhysicsHeat and ThermodynamicsMCQ+4 / −1
An external pressure P is applied on a cube at 0oC so that it is equally compressed from all sides. K is the bulk modulus of the material of the cube and α\alphaα 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:
  1. A
    P3αK{P \over {3\alpha K}}3αKP​
  2. B
    PαK{P \over {\alpha K}}αKP​
  3. C
    3αPK{3 \alpha \over {P K}}PK3α​
  4. D
    3PK α\alphaα
