evaporation and condensation

If the amount of water in air is already high or maximum, the rate of evaporation decreases. Water converts into vapour in the air by the process of evaporation. Evaporation is a physical process where liquid changes into a gaseous state. During this process forces of attraction between particles become strong and this is the reason gas changes into liquid. Now cover the beaker with a lid and stop giving it heat. 69% average accuracy. For example, clothes dry faster on a windy day. Evaporation and condensation are two processes through which matter changes from one state to another. Microscopic view of a gas. This is called evaporation. When you take out a chilled soft drink bottle from the fridge and keep it aside after drinking then after some time you notice small drops of liquid on the surface of the bottle. 2. The drops seem to appear from nowhere, but they actually form from water vapor in the air. Learn. This process is known as the condensation of water vapour. Flashcards. If the surface area is increased, the rate of evaporation also increases. Students understand the concept of boiling and freezing … After some time, water vapour in the air gets cooler and converts into water droplets, like clouds. If the rate of evaporation is greater than the rate of condensation, a net evaporation is observed, and the liquid quantity is reduced and vice versa. It takes place when the vapor in the warm air meets a cool surface and cools down to change its state. became liquid through heat. For water vapor to return to its liquid form, it has to lose some of its heat energy. Causes of Evaporation Evaporation occurs when liquid water turns into a water vapor, with about 90 percent of the water going through such a transformation originating from rivers, lakes and oceans. Rate of Evaporation The National Weather Service in the United States measures the rate of evaporation at different locations every year. Pro Lite, Vedantu This energy causes the molecules to move faster. Boiling water evaporates into thin air. It transports water from the Earth's surface to the atmosphere.

PLAY. Where does that come from? Evaporation: Condensation: 1. Evaporation and condensation happen when these molecules gain or lose energy. How can this be poss… In evaporation, matter changes from a liquid to a gas. Students have a difficult time accepting the idea of invisible particles of water in the air. So, when this vapor comes in contact with cooler temperatures, particles become less energetic and come closer to each other. While condensation occurs when a gas or vapor changes into liquid form, evaporation happens when a liquid substance changes to gaseous form. a month ago. Evaporation is a surface phenomenon. 5th grade. This is because water vapor gets condensed and changes into liquid again. Fighting Condensation Factor #2 – Move Wet Air Out Through Natural Ventilation Natural ventilation uses local wind and temperature differences between the inside and outside of the building. Terms in this set (10) What is evaporation? Evaporation is an endothermic process that is the conversion of a liquid to the vapor state by the addition of latent heat. Evaporationis the change of a liquid to a gas. Take a minute to check out all the enhancements! As the Sun heats water in a puddle, the puddle slowly shrinks. The opposite of condensation is evaporation. Evaporation is the process of a substance in liquid form transitioning into the gas phase. Evaporation and condensation happen when these molecules gain or lose energy in the form of heat. The Macroscopic View. Take a beaker and put water in it. For example, wet clothes dry quickly under sunlight. If they gain enough energy, the molecules near the surface break away. Relation between rate of evaporation and surface area can be written as –, Temperature – Rate of evaporation increases at higher temperatures. Evaporation, Condensation, and Dew Point. The presence of condensation nuclei are critical for the formation of clouds. If the surface area is increased, the rate of evaporation also increases. These molecules escape the liquid and enter the air as gas. Write. How about fog? Although evaporation and condensation are opposite processes, both are caused by water molecules interacting with the warm or cool air around them. Relation between rate of evaporation and temperature can be written as –, Humidity – Humidity is the amount of water vapor present in air. The water seems to disappear, but it actually moves into the air as a gas called water vapor. In the case of liquid as well a small fraction of particles at the surface, having higher kinetic energy, is able to break away from the forces of attraction of other particles and gets converted into vapors. Has someone ever told you that the water falling as snow has always been here, or that the water we use was once dinosaur blood, or that we are drinking someone's sweat, or, worse yet, drinking someone else's… gulp? For example, clothes dry faster on a windy day. If the amount of water in air is already high or maximum, the rate of evaporation decreases. Definitions of evaporation, evapotranspiration, condensation, and precipitation and how these processes relate to saturation water vapor pressure curve.
