Consider a hypothetical situation where we are comparing the properties of two crystals made of atom A and atom B . Potential energy (U) v//s interatomic separation (r) graph for atom A and atom B is shown in figure (i) and (ii) and respectively. It is seen that the potential energy can reach a maximum value of U_(T) at temperature T= 10K . if r_(1) and r_(2) are 0.9999 r_(0) "and" 1.0003 r_(0) for atoms of crystal A , its approximate coefficient of linear expansion can be :-
