1. A gas has one defined state at room temperature whereas a vapour is a substance that is in gaseous and liquid equilibrium at room temperature, at a given pressure. A gas can also refer to a single element of matter with its own unique physical and chemical properties, for example oxygen, nitrogen and neon.
2. Because vapour is actually the gaseous state of an element, vapour particles will be of a single element and may have a definite shape whereas gas particles when observed under microscopic view do not have a definite shape and will be a collection of atoms, ions, electrons and molecules. However both gas and vapour particles are in a random motion, colliding with each other or the walls of the containing vessel when observed under a microscope.
