Think and Explain

Is this label on a household product cause for concern? "Caution: This product contains tiny electrically charged particles moving at the speeds of 10000000 km per hour"

It sounds unstable, put a mr. yuck sticker on it cause it might blow up.

everything contain s tiny electrically charged particles moving at high speed. They're called electrons and belong to atoms.

Using a classical picture of the atoms (as little point electrons moving in orbits around nuclei) one finds that the speed they are moving at would be several millions of km/h. So *everything* contains little charged particles moving at millions of km/h, including your own body! So no cause to worry. (again, this is really not correct as quantum physics reveal that it is incorrect to think of electrons as being little particles moving around the nuclei like planets around the Sun...)

My bad, for some reason when i saw that problem, i just thought if the electrons move fast enough the object will melt. Like when you heat up a piece of metal, the electrons move faster and faster breaking the structure.

What you were thinking about was thermal energy. In that case, one is talking about the average motion of the *atoms* (or molecules). But even at low temperature, the elctrons are moving very fast (in the classical picture) around the nuclei.

Thanks a lot guys for the help
