Difference between boiling and evaporation?

Question

Answer

1)Boiling is occur at specific temprature.2)Boiling is a throughout process.3)Boiling only happens after100'degree.................but ................1)Evaporation is occur at any temprature.2)Evaporation is a surface process.3)Evaporation also happen below 100'degreeThat's all

Answer

In simple words 1 Boiling it's a bulk phenomenon. it's require 100'c/373'k it's require time 2 evaporation1its a surface area phenomenon it's occurs in any degree  that's all

Answer

Boiling vs Evaporation
Boiling and evaporation are two different processes that involve the change of a liquid into a gas. While they may seem similar, there are key differences between the two.

Boiling:
- Boiling is the process in which a liquid is heated to its boiling point, resulting in the formation of bubbles and the conversion of the liquid into a gas.
- Boiling occurs throughout the entire liquid, as it requires the input of heat energy to reach the boiling point.
- The boiling point of a liquid is a specific temperature at which the vapor pressure of the liquid equals the atmospheric pressure.
- Boiling is a rapid process and results in the entire volume of the liquid being converted into a gas at the boiling point temperature.
- Boiling is a cooling process as it removes heat energy from the liquid to facilitate the phase change.

Evaporation:
- Evaporation is the process in which a liquid changes into a gas at temperatures below its boiling point.
- Evaporation occurs at the surface of the liquid, where molecules with enough kinetic energy escape into the air as vapor.
- Evaporation is a slower process compared to boiling as it does not require the entire liquid to reach a specific temperature.
- Evaporation can occur at any temperature, as long as the liquid is exposed to air and has enough thermal energy for molecules to escape.
- Evaporation is a cooling process as it removes heat energy from the liquid surface, leading to a decrease in temperature.
In conclusion, boiling and evaporation are both processes that involve the conversion of a liquid into a gas, but they differ in terms of the mechanism, speed, and temperature requirements. Boiling is a rapid process that occurs throughout the liquid at its boiling point, while evaporation is a slower process that takes place at the liquid surface below the boiling point temperature.
