An external pressure P is applied on a cube at 0°C so that it is equally compressed from all sides. K is the bulk modulus of the material of the cube and α 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
3PKα
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Δ p = – 
= – γΔθ = –3 αΔθ
3 αΔθ K = p
Δθ =
