Why does evaporation happen?
Evaporation happens when a liquid substance becomes a gas.
When water is heated, it evaporates.
The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor.
Heat from the sun, or solar energy, powers the evaporation process..
Why Condensation is the reverse process of evaporation?
While as in evaporation water or water droplets are been heated and converted into water vapours. Therefore in condensation from air droplets are formed and in evaporation the droplets are changed to vapours or gas . Therefore they can be called reverse process.
What is the relationship between evaporation and temperature?
Since the kinetic energy of a molecule is proportional to its temperature, evaporation proceeds more quickly at higher temperatures. As the faster-moving molecules escape, the remaining molecules have lower average kinetic energy, and the temperature of the liquid decreases.
Is the reverse process of evaporation?
Opposite process of evaporation is condensation. During condensation, liquid water is form from water vapour by cooling.
What are the 4 factors that affect the rate of evaporation?
Factors That Affect the Rate of Evaporationtemperature of the liquid. A cup of hot water will evaporate more quickly than a cup of cold water.exposed surface area of the liquid. … presence or absence of other substances in the liquid. … air movement. … concentration of the evaporating substance in the air.
What is evaporation with diagram?
Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure. Evaporation is a fundamental part of the water cycle and is constantly occurring throughout nature.
What is reverse process of evaporation?
Answer and Explanation: The opposite of evaporation is condensation. While evaporation is the process of liquid changing into a gas, condensation is the process of a gas…
What does the rate of evaporation depend on?
However, the rate of evaporation forms depends on external variables such as temperature, humidity and wind speed. Generally, when temperature and humidity are constant, and wind speed increases, the rate of evaporation increases as well.
What is the relation between evaporation and condensation?
Condensation is the change from a vapor to a condensed state (solid or liquid). Evaporation is the change of a liquid to a gas.
How evaporation takes place at all temperature?
True, Evaporation takes place at any temperature. When the air molecule strike the surface, they are going to impart some energy to water molecules. If this energy is sufficient enough to change the phase of water molecules; we experience a phenomenon evaporation. It can occur at any temperature.
What does not affect the rate of evaporation?
The rate of evaporation is depends on some factors like temperature, wind speed, surface area etc. … And for the last case the insoluble heavy impurities can’t affect the process of evaporation. Cause after evaporation the insoluble heavy impurities will still remains the same. It will not evaporate with the liquid.
What is the reverse of condensation?
Powered by. Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor.
What is the reverse of sublimation?
Deposition is a thermodynamic process. The reverse of deposition is sublimation and hence sometimes deposition is called desublimation. One example of deposition is the process by which, in sub-freezing air, water vapor changes directly to ice without first becoming a liquid.
What is evaporation very short answer?
Evaporation, the process by which an element or compound transitions from its liquid state to its gaseous state below the temperature at which it boils; in particular, the process by which liquid water enters the atmosphere as water vapour.
Why evaporation is a cooling process?
Actually, evaporation is a cooling process because when liquid turns to gas, it needs more energy and so it has to take that energy from its surrounding. The energy is in the form of heat and when the energy (heat) leaves with the evaporating liquid; surrounding gets cooler.
