Answer. Boiling is a bulk phenomenon. Particles of the bulk of the liquid gain enough energy to change to vapour state. Whereas evaporation is a surface phenomenon.

When the temperature rises, then the process of evaporation occurs, as a result of which the molecules are easily disintegrated at the surface. It is due to this, the process of evaporation is commonly considered as a surface phenomenon.

The kinetic energy of the topmost molecules will get dissipated in air. Melting process is also an example of surface phenomenon. Boiling is the bulk phenomenon because in this the particles of the bulk of liquid gain energy and then get converted into gaseous or vapor state.

Electrolysis process. Process of electrolysis is not a surface phenomenon.

The temperature at which a liquid changes into gas or vapour is known as boiling point. The boiling point of water is 100 C.It is called bulk phenomena because particles inside liquid gains adequate energy to change into vapour state and this happens only at boiling point.

The temperature at which liquid changes into its gaseous state is called as boiling point. During boiling of a liquid, say water or milk, heating is to be done from the bottom of the vessel to bring the temperature of the entire liquid to its boiling point – so it is a bulk phenomenon.

Bulk phenomenon corresponds to the phenomenon in which the whole object or substance is involved in the process and is fully influenced in bulk. Example – Boiling.

Boiling is the bulk phenomena while the rest are surface phenomena. A phenomena where the total molecules in the system are involved is called a Bulk phenomena.

Ans: Yes boiling is considered as bulk phenomenon because total molecules (including interior molecules along with surface molecules) are involved during boiling of any liquid. Whereas during evaporation only surface molecules will involved, so it is considered as surface phenomenon. Boiling is a bulk phenomenon.

Evaporation is a surface phenomenon means the above water will evaporate from the whole water and boiling is a bulk phenomenon it means water particles will evaporate from all sides of container containing water.

Viscosity is a bulk property, whereas surface tension, evaporation and capillarity are surface phenomenon.

Evaporation is a surface phenomenon, whereas boiling is a bulk phenomenon. …

Summary of the answer- in evaporation the molecule at the surface of the work surface of water only get evaporated by Latent heat from environment. By this we can conclude that- Evaporation is a surface phenomenon while boiling is bulk phenomena.
