Again, take a beaker and put water in it. This can be confusing and seen as a contradiction as well since condensation is the result of a drop in temperature and colder conditions in general. a month ago. In a similar way, as water in a pot boils, the level of the water falls. In condensation, matter changes from a gas to a liquid. Condensation, the opposite of evaporation, occurs when saturated air is cooled below the dew point (the temperature to which air must be cooled at a constant pressure for it to become fully saturated with water), such as on the outside of a glass of ice water. Evaporation is a physical process where liquid changes into a gaseous state. After some time, you will notice that water starts boiling and changes into vapor. Pro Lite, Vedantu Evaporation and condensation are two processes through which matter changes from one state to another. By continuing to use this site, you consent to the terms of our cookie policy, which can be found in our. Thus, increase in wind speed increases the rate of evaporation as well. 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. Evaporation, Condensation, and Dew Point. In this process the state of matter changes from liquid to vapor (gas). • Evaporation and condensation are both occurring in natural liquids. The main difference between evaporation and condensation is that evaporation involves a phase change from liquid phase to vapor phase at temperatures below the boiling temperature of the liquid, whereas condensation involves a phase change from vapor to liquid phase. 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. Take a minute to check out all the enhancements! Flashcards. As the temperature increases, the rate of evaporation increases. Evaporation is a surface phenomenon. 558 times.

This phenomenon of change of a liquid into vapors at any temperature below its boiling point is called evaporation. Condensation is the change of the physical state of matter from gas phase into liquid phase. 5th grade. The dew that forms on grass overnight is another example of condensation. Save. became liquid through heat. Condensation happens when molecules in a gas cool down. It can also be defined as the change in the state of water vapor to liquid water when in contact with a liquid or solid surface or cloud condensation nuclei within the atmosphere. How about fog? Following factors affect rate of evaporation –, Surface Area – Evaporation is a surface phenomenon. Evaporation is the process of changing liquid water into water vapor (a gas). Microscopic view after condensation. Finally these molecules collect together to form a liquid. Condensation is a physical process where a gas changes into a liquid state.

As a result they slow down. If the surface area is increased, the rate of evaporation also increases. For example, clothes dry faster on a windy day. Let us first understand the water cycle. Learn. After some time, water vapour in the air gets cooler and converts into water droplets, like clouds. For example, we spread clothes out to dry them faster. The two terms are related, but they have opposite meanings. "Net" condensation means that the condensation rate exceeds the evaporation rate causing liquid water droplets to form. It takes place when the vapor in the warm air meets a cool surface and cools down to change its state. Evaporation and condensation both are natural phenomena, and together they create the water cycle. In essence, evaporation and condensation usually refers to a state of matter or a phase change between vapour and liquids. boiling point. Microscopic view of a gas. Mechanisms that result in warm and cold cloud formation. Ironing of Clothes. packard5th. After translating an article, all tools except font up/font down will be disabled.
