Question

How does the boiling point affect evaporation?

Answer 1

Evaporation is the process in which a substance changes from one state to another. Evaporation depends on several factors like the surface area, humidity, temperature and the wind speed.

Complete step by step answer:
- Evaporation is the process in which a liquid turns into a gas and this is also known as vapourization. This phenomenon only occurs on the surface of the water. The process of evaporation is a slow process and it is affected by several factors.
The various factors are mentioned below:
- Effect of surface area: the process of evaporation increases with the increase in the surface area and it is because the larger the surface area of the water exposed to air the more of the molecules will evaporate.
- Effect of temperature: the process of evaporation increases with the increase in temperature as the kinetic energy of the molecules increases. If the boiling point of a compound is high, then the process of evaporation will take place after they reach the boiling point.

Additional Information :
Other factors which affect the process of evaporation are:
Effect of the wind speed and the effect of humidity and there are some other minor factors which also affect the process of evaporation.

Note: Students usually get confused between the process of evaporation and boiling. The process of evaporation is a surface phenomenon while the process of boiling is a bulk phenomenon. The process of evaporation can occur at any temperature but the process of boiling only takes place at the boiling point of the substance.
