Question

Write the differences between evaporation and boiling.

Answer 1

Hint: This question is a theoretical one and can be solved defining the processes of evaporation and boiling. Evaporation is the process of conversion of the state of matter from the liquid to the vapor (gas), whereas, boiling is a process when the liquid starts to vaporize or boil.

Complete answer:
Let us go through the differences between evaporation and boiling.
Evaporation: This process can take place at any temperature. This process occurs at a slower rate. The movement of the particles will not be the same. There is a temperate difference at each layer of the liquid. Evaporation is a natural process. The bubble formation does not take place. The external energy or the source is not needed for this process to take place.
Boiling: This process takes place at a temperature higher than that of the boiling point of the liquid. This process takes place at a faster rate until it starts. The movement of the particles will be the same. The temperature is uniform throughout the liquid present in the container. Boiling most of the time is not a natural process. The bubble formation takes place. The external energy or the source is needed for this process to take place.

Note: The summary of the difference between the evaporation and boiling, that is, the important points to be remembered are: evaporation takes place on the surface of the liquid, whereas, the boiling takes place throughout the length of the liquid. The rate of the boiling process is faster than the rate of the evaporation process.
