How would a superconducting material at room temperature be useful?

Most superconducting materials have to be very cold. Getting materials this cold tends to require the use of a lot of energy. The idea behind superconducting materials is to transfer energy more efficiently, without energy loss due to such things as heat. So, expending energy to save energy defeats the point.
With a superconductive material at room temperatures, we could do things like send electricity for long distances without losing any of the electricity along the way. Electricity could be generated in wind farms on the plains and sent to houses on the coasts with no loss. It could make computers more efficient as well by allowing the creation of super-fast electronic switches. This is done by sandwiching a thin insulating layer between two pieces of superconductive material.

What happens to the particles when the matter freezes?
This would depend on the freezing temperature of the material, and therefore, also on the type of material in question. At absolute zero, a theoretical temperature, all motion of the particles stops.
Where are superconductors used?
SuperConductors are electrical conductors having zero resistance. Superconductivity is referred as a "macroscopic quantum phenomenon". Superconductivity is reached at extreme cold temperature close to absolute zero. SuperConducting material will repel a magnetic field. normally a magnet hovering over a conductor will induce electrical currents in that conductor, this induced current is an exact mirror of the field that would have otherwise penetrated the superconducting material causing the magnet to be repulsed. This phenomenon is known as strong diamagnetism also referred as the "Meissner effect". The Meissner effect is so strong that a magnet can actually be levitated over a superconductive material. Superconductivity has so many application fields, and we have just mentioned one, "The levitation", which can make trains float over the rails. Superconducting magnets will significantly reduce power consumption in contradictory to traditional electro-magnets - CERN projects are a good example that uses huge superconductivity to accelerate particles. Another application field is biomagnetism, like MRI (magnetic resonance imaging) and another commercial application is the electrical generators wounded with superconductive wires which operates far more efficiently than the generators with copper wires.SuperConductivity has unlimited benefits in many other domains, we may also manufacture superconducting cables to transfer commercial electricity to the cities or integrate superconductivity concept into microchips.
Can a material gain energy and not change temperature?
Yes quite possible. This occurs at the change of state. As water gets changed into steam heat will be supplied but the temperature would remain at the boiling temperature.
Materials with a high specific heat can absorb a lot of energy and show little change in temperature?
Yes. Specific heat capacity is the amount of heat energy required to change the temperature of the material, so a material with high specific heat needs a lot of heat energy for its temperature to go up.
What phases does a solid go through when heated?
Some materials have multiple solid phases, others do not. It depends on the particular material and also on the temperature and pressure conditions. If you want to know what phases a specific material at a particular pressure goes through as it is heated from temperature X to temperature Y, that would be answerable by looking at a phase diagram for that material, but the generic form cannot be answered.
Recent discoveries have led some scientists to hope that a material will be found that is superconducting at room temperature Why would such a material be useful?
Explain why a scientist would want to find superconductors
What would happen if the power source was removed from the circuit?
In almost all cases, the circuit would cease to operate in a small fraction of a second. The one important exception is the case of a superconducting ring, in which a current can continue to circulate indefinitely without a power source, as long as it is kept at or below its superconducting temperature.
Why would a material of low density be useful?
For making something that floats.
Why is chromosomes useful?
Chromosomes are are your genetic material. Without them you would not exist.
Why would gold be a useful material for people to use as the stone age?
it bends and its shiny?
What would happen if you cooled a computer to the point of superconducting?
"To the point of superconducting" makes little sense in this context. What, specifically, is superconducting? the little wire traces between the transistors? If you made a computer "really really cold", you can overclock it / run it at above nominal speeds. This is really the only reason to "supercool" a computer.
How many btu's would it take to raise the temperature 1 degree?
This question can not be answered without know much more information. Such as the material that needs to have its temperature changed. How much of that material there is.

What is Excessive VELOCTY in pipes?
That would dependon the material (type of piping) and the the temperature of the liquid passing through

Where is the electromagnet the strongest?
The strongest type of electromagnets are superconducting electromagnets. Usually these superconducting electromagnets are immersed in liquid nitrogen or liquid helium to cool them to near absolute zero. === === For non-superconducting electromagnets, the strongest electromagnets would have the greatest ampere turns over a large area. The core of the magnet would be a highly ferromagnetic material, such as iron, or a mixture of a ferrite and a ceramic. Very strong electromagnets used for lifting machinery have both poles on the bottom side which will maximize the magnetic field produced. Non-superconducting electromagnets will saturate and stop producing magnetic fields at about 2 teslas or so. This is the limit of magnetic strength of ordinary electromagnets.
