Why at a particular temperature does resistivity of an element reduce to zero?

satguru

I daren't try and summarise it as all I knew was if you drop the temperature near absolute zero many metals lose their resistance. This site has a nice video showing how the molecules separate to allow the charge through though so if you can understand the nuclear physics as well that's even better (I couldn't). http://www.chm.bris.ac.uk/webprojects2006/Truscott/ Here's a simpler version as well http://www.howstuffworks.com/question610.htm Nov 03 09, 5:29 PM

It is known that at a particular atmospheric pressure and temperature, an element or a compound can only exist in one state; either solid, liquid or gas. However, why is that we can have both the solid iodine and iodine solution in the lab, where the temperature and atmospheric pressure are constant? Why does our height reduce as we grow old? What temperature is absolute zero? What is the only mammal that survives below zero degrees body temperature and why doesn't its body freeze? Which temperature scale stars at absolute zero?

1 Add an Element Take the letters of the word or words given, add the letter or letters for the element given and you have the name of a scientist. Sometimes you must rearrange the letters. e.g. RICE + uranium = CURIE (rice+u) Mixed Elements Average 10 Q minch Jun 21 04 1251 plays 2 Tin: An Interesting Element We come into contact with tin almost every day, but seldom give it much thought.
