Evaporation 1=Evaporation occurs even below boiling point temperature. 2=It occurs only at the surface. 3=Evaporation causes cooling. Boiling. 1=Boiling occurs at particular temperature. 2=It occurs in the bulk of liquid. 3=It does not causes cooling

Evaporation vs. Boiling
Evaporation and boiling are both processes that involve a liquid turning into a gas, but they differ in several key ways.

Evaporation:
- Evaporation is a slow process that occurs at the surface of a liquid.
- It takes place at temperatures below the boiling point of the liquid.
- The molecules at the surface of the liquid gain enough energy to escape into the air as vapor.
- Evaporation can happen at any temperature, even at room temperature, and does not require the entire liquid to reach a specific temperature.
- It is a spontaneous process driven by the heat energy from the surroundings.
- Evaporation leads to the cooling of the remaining liquid as the molecules with higher kinetic energy leave the surface.

Boiling:
- Boiling is a rapid process that occurs throughout the liquid.
- It happens at a specific temperature called the boiling point of the liquid.
- The entire liquid reaches the boiling point, and bubbles of vapor form within the liquid and rise to the surface.
- Boiling requires a constant source of heat to maintain the temperature at or above the boiling point.
- It is a non-spontaneous process that requires an external heat source to provide the necessary energy for the liquid to vaporize.
- Boiling does not lead to the cooling of the liquid, as the heat input is continuously required to keep the liquid at the boiling point.
In conclusion, while both evaporation and boiling involve the conversion of a liquid into a gas, they differ in terms of speed, temperature requirements, energy source, and impact on the remaining liquid.
