What is the difference between gas and vapour?
Answers
Difference between Vapor and Gas
Usually a vapor phase consists of a phase with two different substances at room temperature, whereas a gas phase consists of a single substance at a defined thermodynamic range, at a particular room temperature. Thus, this is defined as the key differences between Vapor and Gas. You can find the major differences in the table below.
Difference between Vapor and Gas
Vapor
Vapor is a mixture of two or more different phases at room temperature, these phases are liquid and gaseous phase.
Vapor has a definite shape of the gaseous particles when observed under a microscope.
Vapor consists of random molecules and atoms moving randomly about.
Vapor is not a state of matter unlike gases.
Vapor is usually formed of a substance above its boiling point temperature.
Gas
Gas usually contains a single thermodynamic state at room temperature.
Gas does not a definite shape when it is observed under a microscope.
Gas also consists of random molecules and atoms moving about randomly.
Gases are a state of matter.
Gases are usually formed above its critical temperature, but below critical pressure.
