Why do metals conduct heat so well?The electrons in metal are delocalised electrons and are free moving electrons so when they gain energy (heat) they vibrate more quickly and can move around, this means that t
Metals are good conductors of heat and electricity because they contain a glut of free electrons. These free electrons are able to move around freely and collide with one another, propagating heat and electricity through the metal. The majority of materials that conduct heat and electricity are m...
Answer: Metals are an excellent conductor of electricity and heatbecause the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions. ...

Why do copper (II) sulfate crystals not conduct electricity? Explain why the copper element has two ion charges. Why do metals conduct heat and electricity? Why does displacing copper using zinc produce a black precipitate? Why is a salt bridge necessary in galvanic...
are composed of atoms and why it is they have the properties they do: for example, why copper and rubies are colored, why metals conduct heat better than glass, why magnets attract an iron nail but not a brass pin, and how superconductors are able to conduct electricity without resistance....
Why do metals conduct heat and electricity? Why does water have a higher boiling point than alcohol even though water is a smaller molecule? Why is evaporation a cooling process? Give a scientific reason. Why do impure molecule have lower melting points?
electricity at room temperature.参考: MY BRAIN carbon 有一个formate 系graphite 佢用左3粒slectron 去form covalent bond with other carbon 由于系3个bond 佢成为左一个plane 最后个粒electron 就系plane 同plane之间自由游离 由于lee 粒electron 系free electron 所以it conduct electricity ...
