Question

Difference between boiling and evaporation​

Answer 1

Answer:

evaporation is slower, occurs only from the surface of the liquid, does not produce bubbles, and leads to cooling. Boiling is faster, can occur throughout the liquid, produces lots of bubbles, and does not result in cooling.

Answer 2

Question

Differentiate between boiling and evaporation.

Answer

Basically boiling and evaporation are two processes that help in the conversion of liquid to gas. They both have several differences and here are some of them.

Here are the differences between boiling and evaporation -:

Boiling

• It occurs at a fixed temperature.
• It is a bulk phenomenon. All the particles gain kinetic energy and turn into gaseous at once.
• It occurs faster than evaporation.
• It doesn't cause a cooling effect at the end.

Evaporation

• It can occur at any temperature below the boiling point.
• It is a surface phenomenon. Particles on the surface of a liquid have a lesser intermolecular force and even after absorbing a little heat from the surrounding, the particles gain kinetic energy and are able to break away and convert into gaseous form.
• It occurs slower than boiling.
• It causes a cooling effect.
