Detailed explanation-1: -All liquids (and even solids) evaporate in the sense that some of their molecules or atoms fly off the surface into the nearby gas. If something blows those molecules away, then more will keep evaporating until the liquid is gone.

Detailed explanation-2: -It turns out that all liquids can evaporate at room temperature and normal air pressure. Evaporation happens when atoms or molecules escape from the liquid and turn into a vapor.

Detailed explanation-3: -In contrast, ionic liquids, which are composed only of ions, cannot pollute the atmosphere because they do not evaporate under normal conditions when they are heated – this fundamental, ever-present, characteristic of ionic liquids is one of the reasons why they are called ‘green’ solvents.

Detailed explanation-4: -Air pressure also affects evaporation. If air pressure is high on the surface of a body of water, then the water will not evaporate easily. The pressure pushing down on the water makes it difficult for water to escape into the atmosphere as vapor. Storms are often high-pressure systems that prevent evaporation.

Detailed explanation-5: -Temperature required: A liquid will evaporate at any temperature above freezing. In the previous example, the water was at room temperature, and it slowly evaporated. If the water was warmer, it would have evaporated faster.
