During evaporation, water rises into the atmosphere and condenses into clouds. When the clouds absorb too much moisture and become heavy, the moisture falls to the ground in the form of precipitation. This is known as the water cycle, which involves evaporation, condensation and precipitation.Know More
The water cycle starts when water evaporates from the ocean surface. Moisture rises and cools, and water vapor forms clouds. Soon, moisture returns to the ground through precipitation. Once water reaches the surface, some of it tends to evaporate back into the air. It also sometimes penetrates the surface and becomes groundwater, which seeps into rivers, streams and oceans. At times, water gets released back into the atmosphere via transpiration, which is the process of water evaporating into the air from the leaves and stems of plants.
Evaporation is the process of liquids changing into gas. It occurs when liquids are either cool or warm. Oftentimes, evaporation happens when liquids are warm. Through the water cycle, water is never lost; it is constantly changed to different forms.
Most of the water that evaporates into the air comes from oceans. Liquids from plants and soil also rise into the atmosphere and form clouds. Snow and ice evaporate even without melting first through sublimation, which is the process of transitioning directly from solid to gas with no intermediate liquid phase.Learn more about States of Matter
Water boils when the thermal energy in the water, which is a type of kinetic energy which causes the water molecules to move around, exceeds the strength of the hydrogen bonds between the molecules, causing them to separate from the other molecules. This breaking of bonds between water molecules consumes any additional thermal energy added, so that water at boiling temperature does not increase in temperature until the phase change is complete. In normal conditions, much of the water vapor almost immediately turns to steam, which is actually composed of droplets of liquid water because it has left the source of heat.Full Answer >
According to the website ScienceBits, the reason breath is visible in cold weather is due to the condensation created when warm, humid air from the lungs collides with the colder, outside air Because frigid air cannot hold as much water vapor as hot air, the resulting saturation of water vapors into the atmosphere becomes visible to the human eye.Full Answer >
Water boils at 100 degrees Celsius because, at that temperature, its vapor pressure equals the pressure of the surrounding atmosphere at sea level. The molecules of liquid are moving too energetically for the outside pressure to keep them in the liquid at boiling temperature.Full Answer >
Condensation nuclei are tiny particles of solid or liquid in the atmosphere that trigger water vapor to begin condensing into water droplets and forming clouds. Any particles that are attractive to water molecules, namely charged or polar particles, are suitable nuclei, but under normal conditions they must be large enough to likely encounter a water molecule. Once this occurs, each additional molecule helps the nuclei attract more molecules.Full Answer >
