malarr Posted July 22, 2010 Posted July 22, 2010 what happens to the atomic structure of the metal or any element when it is rapidly heated...... and why the resistance of any conductor increases with increase in temperature.....
PaulS1950 Posted July 25, 2010 Posted July 25, 2010 The molecules in metals move around (against each other) more when heat is added. Not all conductors lose conductivity when heated - carbon decreases its resistance as it gets warmer.
