Evaporation drives the water cycle. When you have a puddle of water (H 2 O) on a windy day, the wind can cause an increased rate of evaporation even when it is cold out. There is low pressure in space.. Sublimation is the process by which a solid transforms into a gas without passing through the liquid stage. ĭ-văp'ə-rā'shən . Make it an experiment! At normal atmospheric pressure, only some compounds like 'dry ice' (solid carbon dioxide) can go through this process.Most objects need low pressure in their surroundings to go through sublimation. Evaporation is defined as the process of a liquid changing into a gas. Information about evaporation from the DK Find Out website for kids. In nature, evaporation—especially from the oceans—plays a key role in the water cycle by moving water from its liquid state on Earth’s surface to the atmosphere as water vapor. Evaporation happens when atoms or molecules escape from the liquid and turn into a vapor. Water (a liquid) turns into vapor (a gas) when heat energy is applied to raise its temperature to 100°C (212°F). Dictionary Definitions; Evaporation Evaporation meaning. Diagram of water changing to vapor and rising upward. Evaporation, mostly from the sea and from vegetation, replenishes the humidity of the air.

Evaporation occurs when liquid water on Earth’s surface turns into water vapor in our atmosphere. Evaporation, the process by which an element or compound transitions from its liquid state to its gaseous state below the temperature at which it boils; in particular, the process by which liquid water enters the atmosphere as water vapour. Evaporation is a process by which a substance changes from a liquid state to a gaseous state at temperatures below the boiling point of the liquid. Dictionary ! Evaporation from the oceans is the primary mechanism supporting the surface-to-atmosphere portion of the water cycle. The water evaporates into water vapor, the gas phase of water. Menu. Filters Evaporation is defined as the process of a liquid changing into a gas. evaporation meaning: 1. the process of a liquid changing to a gas, especially by heating: 2. the fact of something…. Learn more. Warm water vapor rises up through Earth’s atmosphere. Water from plants and trees also enters the atmosphere. After all, the large surface area of the oceans (over 70 percent of the Earth's surface is covered by the oceans) provides the opportunity for large-scale evaporation to occur. Many factors affect evaporation, but the main driving force is solar energy from the sun. Water in the liquid state is a compound, and the heat breaks up the bonds into water molecules, which is gaseous. This is called transpiration. If you wanted to set this up as an experiment or investigation, one way to set it up is to leave the wet sand in different places ( sun, shade, indoors etc ) and observe how the sand in each place changes over a period of time. Evaporation is when a liquid becomes a gas without forming bubbles inside the liquid volume.If bubbles are formed we are talking instead about "boiling".For example, water left in a bowl will slowly disappear.
