Question

differences between evaporation and boiling

​

Answer 1

Evaporation

• Evaporation is a normal process that occurs when the liquid form changes into the gaseous form; while causing an increase in the pressure or temperature.  

• Evaporation usually occurs on the surface of the liquid being heated up.

• The bubbling effect is not visible in evaporation.

Boiling

• Boiling is an unnatural process where the liquid gets heated up and vaporized due to continuous heating of the liquid.

• Boiling usually occurs on the entire mass of the liquid that gets heated up.

• The bubbling effect is visible during the process of boiling.

Answer 2

Answer:

Evaporation -

• The process of converting liquid to vapours at any temperature below it's boiling point is called evaporation.
• It is a surface phenomenon.
• It is a silent process.
• No external source of heat is required.
• Cooling effect takes place.

ㅤㅤㅤㅤWhereas,

Boiling-

• The process through which any liquid is converted to vapours at a fixed temperature is called boiling.
• It is a bulk phenomenon.
• It is a noisy process.
• Continuous source of heating is required.
• Cooling effect does not take place.
