When cooled this contains almost zero resistance?
Anything with the property of zero electrical resistance is called a super-conductor.
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 is a super conductor and what are some of its uses?
A super conductor is a material which when cooled to a low enough temperature, will exhibit an electrical resistance of zero. Uses include building very powerful electromagnets and Josephson junctions for scanning microscopes.
What is the difference between superconductors and normal conductors?
Normal conductors have resistance which restricts the flow of electricity and wastes some of the energy as heat. The resistance increases with the length of the conductor. Superconductors have close to zero or zero resistance and a few other properties, but the resistance is the most important one because it means electricity can flow more efficiently through it. The drawback is that all the superconductors we know of today have to be cooled down to EXTREMELY low temperatures to achieve superconductivity.
What happened unexpectedly when mercury was cooled to near absolute zero?
The mercury lost all resistance and became a superconductor.

Directly proportional. As temperature goes up, so does resistance (hence supercomputers being cooled to such low temperatures).
What is a material that has no electrical resistance?
The class of materials called superconductors have no DC resistance when cooled below their transition temperature. This temperature varies with the material and is below 20K for metallic superconductors and generally below about 100K for oxide or "High Temperature" superconductors
Which is an example of a superconductor?
A superconductor is a material with extremely low resistance to an electrical current. Many are metals or the like which have been supercooled to temperatures approaching absolute zero. Examples are mercury, lead and tin
How do you measure cooled temperature?
Cooled temperatures are still temperatures!. You can measure them using expansion thermometers down to around -15 deg Celsius. Below that you will probably need a thermocouple.
Cinders?
Cooled volcanic rock material
What are solutes that dissolve better when cooled?
Gases are more soluble at low temperatures.
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.
What are the properties of thermometric material?
when objects are heated or cooled, their temperatures change, along with some of their properties, these properties are known as Thermometric Properties. Examples include: when objects are heated, they expand, when they are cooled, they shrink. Another is, if an object is heated, its' gaseos pressure will increase and will decrease when object is cooled.Read more: What_are_thermometric_properties
Were the first aircraft engines liquid cooled or air cooled?
Almost all of the first aircraft engines were air cooled as this made for a lighter engine.
What material is magma after it is cooled and crystallized?
It becomes igneous rock.
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.
