Boiling- i) It is a bulk phenomena.
ii) The substance changes it's state only at it's boiling point.
iii) It doesn't give a cooling effect.
Evaporation- i) It is a surface phenomena.
ii) The substance does not change only at it's boiling point.
iii) It gives a cooling effect.
EVAPORATION
- evaporation takes place silently
- it takes place at all temp.
- its a natural process
- it takes place only on surface
- rate of evaporation depends on area of free surface
BOILING
- its associated with characteristic sound
- its takes place at all temp.
- to be heated for boiling
- at constant temp. boiling takes place
- boiling takes place at all regions of liquid
- it does not depend on free surface

Three differences between evaporation and boiling?
EVAPORATIONtakes place at the surface of liquid.heating not requiredtakes place at all temperature.results in cooling since heat is absorbed from the surface.BOILINGtakes place throughout the liquid.requires heating.takes place at different temperature.doesnot results in cooling.
What is the difference between the process of boiling and evaporation of water?
Boiling is a greatly expedited form of evaporation. When you heat something to its boiling point, it has enough energy for its molecules to rapidly escape. Evaporation is a much slower action, generally. It is just molecules at the surface gaining enough energy to escape. Both evaporation and boiling are endothermic processes. They will cool what ever the molecules are escaping from.
Boiling and evaporation are both forms of what?
Both boiling and evaporation are forms of vaporization. Vaporization is the process in which a liquid turns into a gas. Boiling is when vaporization occurs throughout the entire liquid, while evaporation is when vaporization occurs only at the surface of the liquid.
What is vaporization at the surface of a liquid that is not boiling?
Vaporization at the surface of a liquid that is not boiling is called evaporation. It is a process in which molecules of a liquid escape into the gas phase without the liquid reaching its boiling point. Evaporation occurs at temperatures below the boiling point of the liquid.
Which is the slow process evaporation or boiling?
Evaporation is very slow at converting liquid to gas compared to boiling.
List 2 similarities and 2 differences between the processes of boiling and evaporation?
Similarities: Both boiling and evaporation involve the phase change of a liquid to a gas. Both processes require the input of energy in the form of heat. Differences: Boiling occurs at a specific temperature (boiling point) for a given pressure, while evaporation can occur at any temperature. Boiling happens throughout the liquid, while evaporation occurs only at the surface of the liquid.
What is the three differences between evaporation and boiling?
Boiling occurs when the vapour pressure becomes equal to the external pressure while evaporation is the escape of molecules from the surface. Bubbles appear in boiling while not in evaporation. Temperature does not effect the rate of boiling while evaporation is fast at high temperature and slow at low temperature.
Give two differences between evaporation and boiling?
Evaporation takes place at all temperatures but boiling at one particular temperature When saturated vapour pressure becomes equal to the atmospheric pressure boiling takes place but evaporation is not so
Differences between evaporation and distillation?
Evaporation is the process of a liquid turning into a vapor at temperatures below its boiling point, while distillation is the process of separating components of a liquid mixture based on differences in boiling points. Distillation involves collecting and condensing vapor back into liquid form, whereas evaporation does not necessarily involve the collection of the vapor.
What is the difference between the processes evaporation and boiling in pure water?
Evaporation is completely natural. Boiling isn't. Hopefully this helps.
Is boiling a form of evaporation or is evaporation a form of boiling?
Evaporation is one of the 3 types of boiling.

What is it when a gas change to a liquid?
It can be called either boiling or evaporation.
What is the difference between evaporation and boiling?
Evaporation is the process of a liquid turning into a gas at the surface, while boiling is the process of a liquid turning into a gas throughout the entire substance due to the application of heat.
What is the sepration method that includes evaporation?
The separation method that includes evaporation is known as simple distillation. Simple distillation involves heating a liquid mixture to separate compounds based on differences in their boiling points. The higher boiling compound evaporates first, leaving behind the lower boiling compound.
Boiling and evaporation are both forms of what?
Both boiling and evaporation are forms of vaporization. Vaporization is the process in which a liquid turns into a gas. Boiling is when vaporization occurs throughout the entire liquid, while evaporation is when vaporization occurs only at the surface of the liquid.
