Resistance goes up creating more heat which eventually leads to an open circuit.

If a magnet is heated to a high temperature it will lose its magnetism.
That will depend on the temperature coefficient of resistance of the device, which could be positive (i.e. resistance increases with increasing temperature), negative (i.e. resistance decreases with increasing temperature), or zero (i.e. resistance is unaffected by temperature changes).
its resistence considerably decreases
it wil expand
the thermistors respond negatively to the temperature and their resistance decreases with the increase in temperature. Since the resistance of thermistors is dependent on the temperature, they can be connected in the electrical circuit to measure the temperature of the body.

Air may be heated using steam, hot water, electrical resistance, warmer air, the warm earth, or a furnace.
The carbon rods have electrical resistance. Thisi causes them to heat when current is passed through them. The water gets heated by the carbon rods.
The resistance will go up.

The Seebeck effect is a phenomenon in which a temperature difference between two dissimilar electrical conductors or semiconductors produces a voltage difference between the two substances. When heat is applied to one of the two conductors or semiconductors, heated electrons flow toward the cooler one. If the pair is connected through an electrical circuit, direct current (DC) flows through that circuit.
No, it has high specific resistance. But not an insulator. Due to high specific resistance it gets heated as current flows through it. So it is used in heating elements of heating electrical gadgets. The most advantage of Ni-Cr alloy is that it is not easily oxidised.
