Water vapor, water vapour or aqueous vapor is the gaseous phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere. [1]

Water evaporates from the Earth's surface and rises on warm updrafts into the atmosphere. It condenses into clouds, is blown by the wind, and then falls back to the Earth as rain or snow.

4 天之前 · Water vapor is a form of water in its gas state, invisible to the naked eye, that exists in the air around us. When water heats up, whether from the sun warming a puddle or steam rising from a hot cup of tea, it changes from liquid to vapor. This process is called evaporation.

2022年2月8日 · Water vapor is Earth’s most abundant greenhouse gas. It’s responsible for about half of Earth’s greenhouse effect — the process that occurs when gases in Earth’s atmosphere trap the Sun’s heat.

Water can exist as a solid, liquid, or gas at typical conditions found on Earth. As we learned, the process of liquid water becoming water vapor is called evaporation and this process absorbs or requires energy. The opposite process is called condensation, where water vapor becomes liquid water, releasing energy.

2024年5月21日 · Water vapor is the gaseous form of water that permeates the Earth's atmosphere. This moist gas affects the Earth by altering the world's overall climate. The hydrologic cycle demonstrates how water becomes vapor.

Water vapor is a gas phase of water that is also known as aqueous vapor. Generally, it is obtained from the evaporation or boiling of liquid water and also sometimes from the sublimation of ice. Water vapor is transparent as most constituents of the atmosphere are transparent.

Water vapor is water that is in the form of a vapor, or gas. It is a part of the water cycle. When liquid water is heated to boiling point, 100 °C (212 °F), it turns into vapor. Water vapor can also be produced directly from ice; this is called sublimation. Steam is …

Water vapour is the primary form of atmospheric moisture. Although its storage in the atmosphere is comparatively small, water vapour is extremely important in forming the moisture supply for dew, frost, fog, clouds, and precipitation. Practically …

Water vapor absorbs more of the infrared light (heat radiation) emitted by Earth's surface than carbon dioxide (CO 2) or methane (CH 4). About 60% of the natural greenhouse effect under a clear sky is due to water vapor, and water vapor is the most important feedback term in all mathematical models of climate change.
