Heat and electricity are both forms of energy. Electricity is a form of energy that can be easily stored and converted from potential energy to kinetic (working) energy. Heat is generally given off as "waste" or energy that wasn't used in a system. If we compare the flow of electrons with flow of water, the heat in the system will be any water that is leaked from the pipes due to inefficiency of the system that was build.
Why is it warm near an incandescent light bulb?
Like I mentioned above, energy that is not used in a system is given off as waste in the form of heat. Incandescent light bulbs is one of the most inefficient system. Only around 10% of energy is converted into electricity or visible light, and around 90% of the energy is given off as waste and thus the heat.
What is a superconductor? What are they used for in real life? You may have to look this up. How could one make a metal a superconductor?
A superconductor is a substance capable of conducting electricity current with practically no resistance. Due to it's nature, superconductors can create large magnetic fields, that are extremely useful in MRI devices, superconductive trains that literally floats on the rail to eliminate friction. Most metal can become superconductors when at it's critical melting points. Example for aluminum to become superconductive requires the medal to be melted to -457 degrees.

What is Ampere's Law?
Ampere's Law relates the relationship between magnetic field an current. Mathematically it can be written as the line integral of the magnetic field around some closed loop is equal to the times the algebraic sum of the currents which pass through the loop.
If current of the same size flows in the same direction in two electric wires placed side by side, what happens?
It will attract each other.
It will attract each other.
What happens if current of the same size flows in opposite directions in two electric wires placed side by side?
It will repel each other.
