States of Matter - Science Theater 30

If water is in solid form, does the atoms in this solid state--move or vibrate? If so, does that imply that there exist heat in ice?

And if vibration implies a certain degree of heat in any one substance, then what do you think happens in dry ice during sublimation?

thanks

plasma is an ionised gas. meaning its stripped of its electrons

yea, its used all the time, in lights, for melting metals in furnaces, for cutting metal, infact, plasma is imho the best for cutting steel plate.

basically you take a gas and pump it through a nozel, then you take another inert gas and pump it outside the other gas as a shield from atmosphere and you pass an electric current through the inner, active gas, this causes it to heat up to usually around 26000 degrees celcius and voila, industrial plasma cutting :D

Cool. It had not occurred to me that plasmas were used in everyday industrial applications.

And then I was reminded of the many uses of "cold" plasmas (plasma balls, fluorescent lights, etc...) To accommodate these as well, I'd vote for a "YouTube" definition of something like: "An electrically conductive gas that can form structures"

for a practical explanation to the people of youtube, superheated gas is the best explanation, and in a practical application, aka, when used to cut metals, it has the same application and basic setup of another gaseous cutting method.
