1.	A uniform pressure p is exerted on all sides of a solid cube of a meterial at temprature `t^(@)C`. By what amount should the temperature of the cube be raised in order to bring its original volume back to the value it had before the pressure was applied ? K is the bulk modulus and `alpha` is the coefficient of linear expansion of material of solid cube.
Answer» Bulk modulus of elasticity `K = (P)/(Delta V//V) or (DeltaV)/(V) = P/K` But `(DeltaV)/(V) = gamma Delta t` or `Delta t = (Delta V)/(V) xx 1/(gamma) = P/K xx 1/(gamma) = (P)/(K xx 3 alpha)`.
