The electrical conductivity of a conductor increases with increasing temperature
An electrical current flows through a conductor because it provides little to no resistance to the movement of electrons. Typically, good electrical conductors include metals, metal alloys, electrolytes, even some nonmetals like graphite and liquids like water.
Metals, aqueous salt solutions (ionic chemicals dissolved in water), graphite, and the human body are a few examples of conductors.
A conductor makes it simple for current to flow through it. Insulators prevent electricity from passing through them. On the surface of conductors, there is an electric charge. In an insulator, there are no electric charges. Keeping conductors in a magnetic field prevents them from storing energy.

Answer:
Explanation:
From the equation attached , is reduced. This is because reduction is equivalent to decrease in the oxidation number. In the equation , The oxidation number of Ni is reduced from +2 to 0.
NB, The oxidation number of a neutral atom is zero
Answer:
Will up 2NO
Explanation:
The future gas particle will be increased by about 4.2. (estimated) Pressure is absorbed, and by the gas, created heavier.
A-Locations M and O are at the poles.
Explanation:
Locations M and O are located at the poles because they receive sunlight that is spread out over a large surface area. The poles receive sunlight at an angle to the surface and it causes the rays of the sun to spread out in all direction.
- At the equator, sunlight impinges directly on the surface and the solar radiation here is very much.
- It is important to know that the sun is overhead directly at the equator.
- The earth is tilted at an angle to sun and therefore, areas around the polar region will receive sunlight that is spread out in different directions over a large area.
- Away from the pole, the equator is directly facing the sun and it receives direct sunlight.

Answer:
2AlF₃ + 3Li₂O —> Al₂O₃ + 6LiF
Explanation:
AlF₃ + Li₂O —> Al₂O₃ + LiF
The above equation can be balanced as follow:
AlF₃ + Li₂O —> Al₂O₃ + LiF
There are 2 atoms of Al on the right side and 1 atom on the left side. It can be balance by writing 2 before AlF₃ as shown below:
2AlF₃ + Li₂O —> Al₂O₃ + LiF
There are 6 atoms of F on the left side and 1 atom on the right side. It can be balance by writing 6 before LiF as shown below:
2AlF₃ + Li₂O —> Al₂O₃ + 6LiF
There are 2 atoms of Li on the left side and 6 atoms on the right side. It can be balance by writing 3 before Li₂O as shown below:
2AlF₃ + 3Li₂O —> Al₂O₃ + 6LiF
Thus, the equation is balanced..!
