temperature of the cube

A uniform pressure P is exerted to all the sides of a solid cube at temperature T°C.By what amount should the temperature of the cube be raised in order to bring its volume back to the volume it had before pressure was applied ?

If B is the bulk modulus, then B = PV/ΔV (ignoring the -sign)

So, ΔV = PV/B

Now for zero change in Volume,

ΔV = V2 - V = Vγ(T2-T)

So, using these two relations,

ΔT = P/Bγ where B=bulk modulus, γ=coeff. of volume expansion
