The difference between evaporation and distillation is that in the former, only liquids evaporate while in the latter both liquid and gas phase compounds are present. Evaporation is a process in which molecules from a liquid or solid phase change to the gas phase. Distillation is a type of evaporation that separates liquids based on differences in volatility.
In order for either process to work, there needs to be a source of heat and an agent that helps the vapor form, such as steam. This allows for separation between substances because each substance has its own boiling point and will evaporate at different temperatures.
When it comes down to it, distillation and evaporation are very similar processes that can help us separate compounds into individual components with different properties.
In simple terms, it can be said that evaporation takes place at lower temperatures than distillation which means that lesser volatile compounds will evaporate compared to those which will remain behind due to their higher boiling points.

What is Evaporation?
Evaporation is the process of a liquid turning into vapor. it is also known as the phase change from liquid to gas that only occurs on the surface of a liquid rather than throughout its entire mass of it because molecules at the surface have more energy and escape into the atmosphere where they become gaseous.
Evaporation is most commonly associated with water, but it can happen with any liquid or solid that has a low boiling point such as alcohol and salt. The rate of evaporation depends on temperature and wind which will evaporate liquids at different speeds.
This process can happen quickly or slowly depending on how much water is available and how warm it is outside, which makes sense since temperature affects molecules’ average kinetic energy.
When there’s not enough water for evaporation to take place, then you’ll see condensation occur instead as excess vapor turns back into liquid form.
Condensation happens when atmospheric pressure decreases due to an increase in altitude (or distance from Earth’s surface), causing lower temperatures which result in less kinetic energy for those particles so they slow down the evaporation process.
What is Distillation?
Unlike evaporation, which is a natural process, distillation is an artificial and modernized process. This is a technique that separates the purest liquid form from other liquids. It is based on the different boiling points of different liquids. This is due to the different forces of the different intermolecular forces present in the material. Since each type of liquid has a different boiling point, so does the thermal energy required to break the bond.
Distillation is basically used to separate liquid mixtures or mixtures. This is the process of boiling and condensing the liquid. The liquid is heated to the boiling point and boiling point. The temperature is then maintained until the complete vaporization of the critical liquid. If so, use a condenser to return the vapor to the liquid phase.
Major Difference Between Evaporation And Distillation
- During distillation, when the liquid reaches the boiling point, the liquid forms bubbles. However, during the evaporation process, the bubbles do not form bubbles because the liquid does not reach the boiling point.
- Distillation is the process used to separate and purify liquids. However, evaporation does not always occur.
- During the distillation process, thermal energy must be supplied to the molecules of the liquid. This is done to ensure that the liquid molecules are in the vapor state. However, evaporation does not require an external thermal energy supply. Instead, the molecules are energized when they collide in the process. It then uses that energy to release the molecule into a vapor state.
- Evaporation is a natural process and distillation is a proven process. It is performed in the laboratory using the equipment.
When you think about the basics of the universe, you are probably thinking about the problem. It is all around us and is seen in three different phases: solid, liquid, and gaseous.
A substance can change its physical state between these three stages. This is a phenomenon called “phase shift” and can occur at different temperatures.
Evaporation occurs when there is sufficient thermal energy to break down the intermolecular attraction force in the liquid. When this happens, the liquid molecules are released into the gas phase.
The boiling point of some substances occurs at certain temperatures. When this happens, the vapor pressure exerted by the gas-phase material is equal to the atmospheric pressure. This phenomenon is the basis of the distillation process.
More importantly, boiling is the main difference between evaporation and distillation. The evaporation process occurs below the boiling point of the liquid and the distillation occurs at the boiling point.
There are other differences as the two processes are not very similar. They depend on specific factors that may seem similar, but in general they are very different.
