Conductors|Some Facts

Can we say that all free electrons move in the same direction in a conductor when some potential difference is applied across it ?

The given table lists some materials as conductors or insulators. Which is listed incorrectly in the table?

A current carrying conductor is connected with a cell, after some time temperature of conductor is increased by 1 unit. The percentage change in its resistivity is (Here alpha is temperature coefficient of resistivity)

What is an electrical conductor ? Give some examples.

Some charge is being given to a conductor. Then its potential : -

The fact that the conductance of some metals rises to infinity at some temperature below a few Kelvin is called
