Statement - I:- Schottky and Frenkel defects are also called thermodynamic defectsStatement - II:- Both Schottky and Frenkel defects increases with increase in temperature.

In Schottky and Frenkel defects do not disturb  the stoichiometry of the solid hence these are intrinsic or thermodynamic defects and both defects are increases with increase of temperature due to increase of randomness
