Question

Write the factors that affect the process of evaporation?explain with suitable examples

Answer 1

Factors affect evaporation are as follows-

1. pressure-PV=nRT as pressure increases temperature increases too hence increasing pressure leads to increase in evaporation.

2.temperature-when temperature increases water evaporate fast because as temperature rises it converts more molecules of water into gaseous for.

hope it will help you.

Answer 2

Answer:

Surface area, wind speed, humidity, pressure, and temperature are some of the factors that affect the process called evaporation.

Explanation:  

• The transformation of water from a liquid to a gas or vapor is known as evaporation.
• Evaporation is the usual mechanism we heard of for liquid water to return to the water cycle as atmospheric water vapor.

There are diverse factors that affect or regulate the process called evaporation:

1. Temperature:

• As the temperature rises, the rate of evaporation also rises.
• Water boils at 100 degrees Celsius (212 degrees Fahrenheit), yet it starts to evaporate at 0 degrees Celsius (32 degrees Fahrenheit); it simply happens very slowly.
• So, we can see temperature and evaporation have a direct relationship with each other. With the decrease in temperature, there is a decrease in evaporation and vice versa.  

2. Surface area:

• The rate of evaporation rises if there is an increase in the surface area.
• For example, If you keep the same liquid in a test tube and a china dish, the liquid in the china dish evaporates faster because the china dish has a large surface area compared to the test tube.

3.   Humidity:

• If there is an increase in humidity, there will be a decrement in the rate of evaporation.
• Wet clothing, for example, does not dry quickly if the surrounding air is damp, and damp garments in the home take a long time to dry on a rainy day.

4. Wind speed:

• As the wind speed increases, the evaporation rate increases.
• Let's consider the liquid molecules, that have just escaped being swept away by the wind blowing over the liquid's surface.
• This raises the likelihood of additional liquid molecules escaping.

5. Pressure:

• The drop in air pressure causes more evaporation.
• Wet things, for example, dry quickly on the mountain top, where air pressure is lower than at sea level.
