Question

State three differences between evaporation and boiling.

Answer 1

Hint: Boiling starts taking place after the solution reaches a particular physical condition and that is why there is a chance of boiling or evaporation. The level of these two phenomena differs according to the changing physical properties like the temperature and pressure.

Complete step by step solution:
There are some common differences between evaporation and boiling because of the two physical changes. The common differences are given in specifically comparing the two physical characters.
The process of boiling takes place at a specific temperature which is known as the boiling point of the liquid. Only after reaching the boiling point the change of state occurs by boiling. The evaporation is the process which occurs at a big range of temperature when introduced to the liquid. The evaporation starts changing the state of the liquid even before reaching the boiling point.
The process of boiling is really fast because the change of state only occurs after reaching the boiling point. This is why at that temperature the change of state is easier making the process fast. Evaporation is a slow process which is because of the high range of temperature before boiling point is the condition in which evaporation can occur.
The boiling is the process where the change of state occurs from the whole liquid that is subjected to a boiling temperature with energy coming from a specific energy source. The evaporation process occurs as a surface phenomenon and the vapour formation occurs from the surface of the liquid with the energy supplied from the surroundings of the liquid.

Note:
Evaporation is different from boiling because the conditions associated with the two conditions are different from one another. The molecular nature changes in the two states based on the physical state around the liquid and the attraction between the molecules.
