Is a glass rod a conductor or insulator?
Previous answer: Insulator because particles cannot pass through glass. Correct answer: A glass rod is a good conductor because electrons are able to move freely within its region according to the law of conservation of charges. If you have done an experiment about it, you will find out that when you rub a glass rod with silk, a glass rod will be come positively charge, and this means that the electrons get transferred away to other objects, leaving that glass rod a deficit of electrons. This theory is based on the law of electrostatics.
Can water be used as an insulator?
Pure water is an insulator, but in the "real world", water usually has impurities - notably ions - that actually make it a good conductor. This is theory; I don't think it is practical to use water as an insulator.

Is carbon or tin a better conductor?
This depends on the structure of carbon. In the metastable diamond structure, carbon is an insulator. In a stable graphite structure carbon is known as a 'zero band gap' conductor meaning it will conduct electrons with a small input of energy. A carbon nanotube is one of the best known conductors of electricity because of overlapping 'p orbitals'. Tin is a better conductor of electrons compared to carbon ( generally, unless you are talking about carbon nanotubes). This is due to the band theory of solids. The low energy orbitals of carbon do not 'split' and overlap at large distances. The higher energy orbitals of tin do 'split' and overlap at larger distances allowing for electronic conduction.
What keeps things cooler- plastic wrap or aluminum foil?
A plastic is a an insulator or a bad conductor of heat where as a aluminium is a good conductor of heat.The response to heat by any material lies in it's structural pattern,if more number of free electrons exist in the structural form of the object more will be the conductivity of the material.This pattern can also be explained on the basis of the band theory which states that there exists two band,valence band and conduction band.when the number of the electrons in the conduction band increases the conductivity increases.In case of plastic which is a polymer few free electrons exist as compared to aluminium hence is a insulator where as aluminum is a conductor or the heat energy can easily travel through the foil hence FOR KEEPING THINGS COOLER PLASTIC IS BETTER because the heat energy cannot travel through the plastic and heat up the things
Screwdriver handle conductor or insulator?
The metal part itself would be a conductor in theory but the handle would be an insulator as it is usually rubber or plastic.
Use the electron theory to explain how insulators and conductors work?
the same way an insulator and a conductor will work with out the electron theory!
Differentiate in between conductor and semiconductor and insulators using band diagram?
Conductor-one which conducts(allow current)electric city in all condition. Semiconductor-One which behaves like conductor as well as insulator depending on condition. Insulator-one which donot conduct(allow current)electric city in all condition

When was Theory in Practice created?
Theory in Practice was created in 1995.
When did Theory in Practice end?
Theory in Practice ended in 2002.
What is the relationship between theory and practice?
Theory is an idea. Practice is what someone does. A person can take a theory and put it into practice to prove or disprove it.
How does a theory develop?
Theory-practice-theory take existing theory in education, apply to distance learning, develop new theory Practice-research-theory see what is happening in distance learning, submit to research, develop theory from results Theory-theory-research/practice build on an initial theory to develop a second theory, then apply and test it
What is the message of the saying " Theory without practice is empty and practice without theory is blind.''?
