1.Superconductivity: Materials are said to be super conducting when they offer no resistance to the passage of electricity. In this state the materials become diamagnetic.
2. It is because glass is supercooled liquid which flows in the downward direction under its own gravity.
3. stoichiometric defect is also called as intrinsic defect as do not disturb the composition of the solid
