The presence of condensation nuclei are critical for the formation of clouds. In condensation, matter changes from a gas to a liquid. This process is known as the condensation of water vapour. Where does that come from? While condensation occurs when a gas or vapor changes into liquid form, evaporation happens when a liquid substance changes to gaseous form. Now cover the beaker with a lid and stop giving it heat. Matter can exist in three different states: solid, liquid, or gas. In evaporation, matter changes from a liquid to a gas. In essence, evaporation and condensation usually refers to a state of matter or a phase change between vapour and liquids. If the surface area is increased, the rate of evaporation also increases. Condensation is the change of the physical state of matter from gas phase into liquid phase. The water seems to disappear, but it actually moves into the air as a gas called water vapor. These molecules escape the liquid and enter the air as gas. (It should be noted that solids, like ice, can also evaporate or be transformed directly into a gas without first becoming a liquid. It takes place when the vapor in the warm air meets a cool surface and cools down to change its state. Find out more in this Bitesize KS2 Science Explainer. The water vapor, which is in gaseous form rises in the atmosphere. The heat from the sun rays turns the water from the river, ocean, lakes and all other water bodies in nature to water vapor. Evaporation and condensation. Evaporation happens when a liquid is heated. Indoor swimming pools evaporate a lot of water. During this process forces of attraction between particles become strong and this is the reason gas changes into liquid. When a gas is cooled sufficiently or, in many cases, when the pressureon the gas is increased sufficiently, the forces of attraction betweenmolecules prevent … For example, wet clothes dry quickly under sunlight. 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.

Evaporation and condensation are two processes through which matter changes from one state to another. This is a reverse phenomenon of vaporization. Accessible across all of today's devices: phones, tablets, and desktops. The lower the temperature, the higher will be the rate of condensation. Evaporation is the opposite of condensation, the process of water vapor turning into liquid water. Edit. became liquid through heat. This is because water vapor gets condensed and changes into liquid again. 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. Relation between rate of evaporation and surface area can be written as –. "Net" condensation means that the condensation rate exceeds the evaporation rate causing liquid water droplets to form. Match. Terms in this set (10) What is evaporation? Mechanisms that result in warm and cold cloud formation. Pro Lite, Vedantu After a minute when you will take out the lid you will see water droplets on one side of the lid. This energy causes the molecules to move faster. In evaporation, the liquid molecules absorb energy from the surrounding to become gas molecules. Well as we know that particles of matter are always moving and are never at rest it means they possess different amounts of kinetic energy at different temperatures. If the surface area is increased, the rate of evaporation also increases. Flashcards. dametaiteacher. In this process the state of matter changes from liquid to vapor (gas).
