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 else can I help you with?
Would a knowledge of density be useful in choosing a material with which to construct a 10-kilogram barbell?
Yes, knowledge of density would be useful in choosing a material for a 10-kilogram barbell. Different materials have different densities, which affect the size and shape of the barbell. For example, a denser material would result in a smaller barbell, and vice versa.
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.
Is glass viscous at room temperature?
Glass is not considered viscous at room temperature. It is a solid material that does not flow or deform over time like a viscous liquid would.
Can a material gain energy and not change temperature?
Yes, a material can gain energy without changing temperature through a process called phase change, where the energy is used to change the state of the material (solid, liquid, gas) rather than increase its temperature. Examples include melting ice or boiling water.
Does the same amount of different material need the same amount of heat to have the same change in temperature?
No, different materials have different specific heat capacities, which refers to the amount of heat required to raise the temperature of a unit mass of that material by one degree Celsius. So, the same amount of different materials would not need the same amount of heat to achieve the same change in temperature.
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?
A material that is superconducting at room temperature would revolutionize technology by enabling lossless energy transfer and high-performance electronic devices. This could lead to more efficient power grids, faster computers, and advanced medical imaging devices.
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 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.
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 is Excessive VELOCTY in pipes?
That would dependon the material (type of piping) and the the temperature of the liquid passing through
What would happen to any material if the temperature changes from 12 Celsius to 56 Celsius?
Its internal energy increses
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.
What would be the volume of 2mol of CH4 gas?
The answer would depend on the temperature and pressure. And since you have not bothered to share these crucial bits of information, I cannot provide a more useful answer.
