1. Explain superconductivity 2. Why is the window glass of the old building thick at the bottom? 3. Why stoichiometric defects are also called intrinsic defects?

answered-by-expert Expert Answer
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
