Detailed Solution

Because according to the third law of thermodynamics perfect crystals exists at 0K.
As the temperature increases the chance that a lattice may be unoccupied by an ion increases.
As the number of defects increases with temperature, the defects are called thermodynamics defect.
Defects are the irregularities or deviations from ideal arrangement in entire rows of lattice points.
Hence, the disorder ness or randomness increases in solids when they attain defects.
