what happens when you heat gas?

[fattyjwoods]

i was just revising my homework and I was wondering what will happen if you heat gas so much to a point it is supposed to vaporize. does it vaporize? i mean like when you heat a solid it turns into a liquid and when you heat liquid it turns into a gas. what happens when you heat the gas even more!

You get plasma.

Something like superheated gas? Remember also, some solids do not become liquid upon heating, but rather become gas directly. imp

You get plasma.

 

This is the removal of electrons from the atoms. It's an ionised gas.

 

But long before that if you consider:

 

pV=nKT

 

Increase T and the pressure and volume must increase (this is an ideal gas).

thanks guys

Note that gas can't vaporize, since it's already a vapor. The Cap'n already pointed out ionization/plasma; you could also cause molecular material to decompose into smaller molecules or the constituent atoms, depending on the bond strength, and this may happen first. (e.g. ozone or hydrogen peroxide, where one of the atoms is fairly weakly bound)

well, there is a distinction between a vapour and a gas but its not a phase change such as liquid to gas. its just that a vapour can be condensed by compressing it while a gas requires a reduction of temperature.

yep i get it now

[fattyjwoods]

i get all of it

if a gas phases into a plasma, then why doesn't somebody just filter the carbon dioxide through? lava wouldn't it just be added to the molten rock mixture?

err what?

Lava isnt plasma...
