A gas refers to a substance that has a single defined thermodynamic state at room temperature whereas a vapor refers to a substance that is a mixture of two phases at room temperature, namely gaseous and liquid phase. ... A vapour can co-exist with a liquid or solid when they are in equilibrium state.
