Vapour

Vapour refers to a substance in a gaseous state at a temperature lower than its critical temperature, meaning it can be condensed to a liquid by increasing pressure. It's essentially the gaseous form of a substance that is typically liquid or solid under normal conditions. vapour is often visible as a mist, fog, or cloud, and plays a significant role in various natural and industrial processes, from weather patterns to combustion engines. The term emphasizes the state of matter undergoing a phase transition from liquid/solid to gas, often associated with evaporation or sublimation. The presence and properties of vapour are greatly influenced by factors such as temperature, pressure, and the substance's molecular structure.
