Evapouration is called a surface phenomenon because as we put water in the presence of sunlight with duration in time the temperature starts increasing and the hydrogen bonds of H2O from the surface starts breaking and the dissociated molecules move upward (lighter in nature) and therfore evapouration takes place from the surface but not inside.
Evaporation is a spontaneous phenomenon. The molecules in the liquid possess kinetic energy. All the molecules donot possess the same kinetic energy. The molecules with higher kinetic energy are on the surface of liquids. They can readily overcome the intermolecular attractions and escape into the atmosphere. This phenomenon is known as evaporation. As the molecules with higher kinetic energy keep on escaping the whole kinetic energy of the liquid is lowered. Since energy is directly proportional to temperature. Thus evaporation causes cooling effect.
Evaporation refers to the process of becoming vapor. Evaporation occurs when the sun heats up the earth surface. Evaporation also occurs when water is heated in a cooking vessel.
Evaporation
Factors that affect evaporation include temperature, humidity, wind velocity, exposed surface area, porosity of soil, grain size of soil particles, soil water content, matric potential, and sun intensity.
Evaporation moves the water from the earth's surface up into the atmosphere. It helps to make the water form clouds from water vapour and condensation. It helps to convert the water vapours (its gas form) to water (its liquid form).
why do we say that evaporation is a phenomenon
Water gets converted into vapors. Evaporation is a surface phenomenon.
evaporation is called a surface phenomenon because the particles of liquid gain energy from the surroundings , having higher kinetic energy, is able to break the away from the forces of attraction of other particle . that is why it is called a surface phenomenon
This phenomenon is called evaporation.
Because it takes place at the surface of the liquid.

At the surface of the liquid the phenomenon is called evaporation. In the entire voume of the liquid the phenomenon is called vaporization.
cos the boiling point 100 degree celcius
Evaporation is a phenomenon (change of phase) at the surface of a liquid and boiling involve the entire volume of the liquid.
This change of phase is called vaporization (for the surface of the liquid the phenomenon is called evaporation).
Evaporation can only take place on the surface of liquids because that is where the molecules with the highest kinetic are found. Only molecules with high kinetic energy are free to escape into the atmosphere.
Evaporation is greatest at the surface. The wind and sun and, boiling water on a kitchen stove, all increase the evaporation rate of the water - which is the process of turning liquid water into a water vapour.
