A wire of length L0 is supplied heat to raise its temperature by T. if γ is the coefficient of volume expansion of the wire and Y is Young’s modulus of the wire then the energy density stored in the wire is

The absolute coefficient of expansion of a liquid is 7 times that the volume coefficient of expansion of the vessel. Then the ratio of absolute and apparent expansion of the liquid is
