1.	Crystals are imperfect because the presence of defects upto a certain concentrationA. increases `G` and decreases `S`B. decreases `G` and increase `S`C. increases both `G` and `S`D. decreases both `G`and `S`
Answer» Correct Answer - 2 On account of crystal defects ,`DeltaG` is `-ve` while `DeltaS` is `+Ve` . Defects may arise due to the heat absorbed by the crystals from the surrounding or due to the presence of impurities in the crystal.
