how does gas differ from vapor
Answers
Answer:
Vapour is a mixture of two or more different phases at room temperature, these phases are liquid and gaseous phase. Gas usually contains a single thermodynamic state at room temperature. Gas also consists of random molecules and atoms moving about randomly. Vapour is not a state of matter, unlike gases.
Explanation:
Please mark me as brainliest
1) The vapour in its natural state is a solid or liquid at room temperature. However, a gas in its natural state at room temperature would still be a gas.
2) Vapour is a substance which has experienced a phase change. Gas is a substance which has not, and will not experience a phase change.
3) A gas is a substance above its critical temperature but below its critical pressure, while a vapour is a substance above its boiling point.
4) Gas is one of the 4 states of matter whereas vapour does not classify as such. It is just a substance in gaseous form.
5) Gas cannot be seen while vapours are visible.
6) Vapours can turn back and form into solid and liquid states but a gas cannot.
