Is evaporation called a bulk phenomenon?

Is evaporation called a bulk phenomenon?

Both boiling and evaporation are bulk phenomena.

How does boiling affect evaporation?

Explanation: Boiling point and evaporation have an inverse relationship, that is, the higher the boiling point of a substance, the lower is the rate of its transformation from liquid to gas (or evaporation). The particles are then released in the form of vapor (gaseous phase of the liquid).

Is boiling and evaporation a surface phenomenon?

Answer Expert Verified Evaporation is a Surface phenomenon whereas, Boiling is a Bulk phenomenon. Evaporation is a Surface phenomenon, and can cause Vaporisation only at the surface. which means that only the particles or molecules of the liquids present on its surface change into vapours .

What is the phenomenon of boiling?

Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.

What is meant by 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.

Is boiling surface phenomenon?

Evaporation is a surface phenomenon because in this above water will evaporate from the whole water. The kinetic energy of the topmost molecules will get dissipated in air. Melting process is also an example of surface phenomenon. So boiling will not be the surface phenomenon hence option A is incorrect.

Why is boiling different from 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. Boiling is an unnatural process where the liquid gets heated up and vaporized due to continuous heating of the liquid. Bubbling effect is not visible in evaporation.

Does boiling cause evaporation?

Many factors affect how evaporation happens. Boiling-hot water will evaporate quickly as steam. Evaporation is the opposite of condensation, the process of water vapor turning into liquid water. Boiling water evaporates into thin air.

What do you know about the bulk phenomenon?

Bulk phenomena: The bulk phenomenon is a phenomenon in which the whole object or substance is involved in the process. This phenomena can only occur at the boiling point of the liquid as all the particles inside the liquid gain adequate energy to change into vapour state.

What causes the phenomenon of boiling?

When it is boiling, the saturated vapor pressure of a liquid equals the atmospheric pressure. The saturated vapor pressure of the liquid can be determined from the temperature. When a sudden change occurs, this is the boiling point (phase transition point).

What do you mean by bulk phenomenon?

Bulk phenomena: The bulk phenomenon is a phenomenon in which the whole object or substance is involved in the process. Example – Boiling. In bulk phenomena the total molecules (including interior molecules along with surface molecules) in the system are involved.

Why absorption is bulk phenomenon?

Adsorption is a surface phenomenon and absorption is a bulk phenomenon. Complete step-by-step answer:The molecules undergoing absorption are taken up by the volume and in adsorption, the molecules are taken up by the surface. Hence, adsorption is a surface phenomenon and absorption is a bulk phenomenon.

What is the difference between boiling and evaporation?

while boiling 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 process. During evaporation, the liquid evaporates from the top surface with out heating- say, evaporation of water from the surface of a lake or vesssel.

Is boiling a mass or a bulk phenomenon?

Answer. Boiling is a bulk phenomenon. Particles of the bulk of the liquid gain enough energy to change to vapour state. The entire bulk of liquid and all the molecules including the interior and the surface gain energy to change to vapour state. The heat energy is supplied from the bottom of the liquid.

Is evaporation a bulk or surface phenomenon?

Yes evaporation is the surface phenomenon as the liquid changes into vapours at any temperature with respect to surface.While boiling is the bulk phenomenon as the liquid changes into vapours only at specific temperature (water =100°celcius ) Still have questions?

What is boiling in chemistry?

Boiling is a bulk phenomenon. Particles of the bulk of the liquid gain enough energy to change to vapour state. The entire bulk of liquid and all the molecules including the interior and the surface gain energy to change to vapour state. The heat energy is supplied from the bottom of the liquid.
