The usual value of the surge impedance of a telephone line is When a piece of copper and another of germanium are cooled from room temperature to 80 K then the resistance?
The usual value of surge impedance of a telephone line is 75 ohmsBy: Somorjit LukramTelecom Technical Assistant,NE-II Telecom CircleBSNL Imphal Manipur SSA
What are crystalline structures that conduct electricity without resistance when cooled to a certain temperature?
Superconducting materials.
How much energy is released when a substance is cooled to its original temperature?
It depends on it's original temperature and how much it was heated.
Why boil water and be cooled before getting the pH?
The pH depends on the temperature.
What happens to volume when air temperature increases?
If pressure remains constant, then volume is directly proportional to temperature. Hot air is quite loud.

Is resistance inversely or directly proportional to temperature?
Directly proportional. As temperature goes up, so does resistance (hence supercomputers being cooled to such low temperatures).
What are crystalline structures that conduct electricity without resistance when cooled to a certain temperature?
Superconducting materials.
What happens when you cool a magnet?
If a magnet is heated to a high temperature it will lose its magnetism.
When a parcel of air of air is cooled to the temperature at which it is saturated it has reached what?
When a paracel of air is cooled to the temperature at which it is saturated, it has reached its dew point.
When cooled this contains almost zero resistance?
Anything with the property of zero electrical resistance is called a super-conductor.
Do liquids have fixed temperature?
No. They can be heated or cooled.
What type of welding machine use in spot welding or resistance welding?
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
A material that has almost zero resistance when it is cooled to low temperatures is a....?
Super Conductor :)
Is cooled a verb?
Yes the word cooled is a verb. It is also an adjective to describe something at a lower temperature.
Why are super cooled metals good conductors?
Super cooled metals are good conductors because their super cooled properties allow them to conduct electric currents without resistance. This means no loss of energy.
How do you compress natural gas?
Natural gas is compressed when it is cooled. When cooled to a temperature of -162 Degrees, it becomes liquid.
