evaporation is a surface phenomenon.A.what is the basis of evaporation?B.how does the phenomenon of evaporation takes place?C.comment on the change in t you observe when liquid evaporates.D.how is evaporation related to surface area?
Answers
Answer:
A.Evaporation of water occurs when the surface of the liquid is exposed, allowing molecules to escape and form water vapor; this vapor can then rise up and form clouds. With sufficient energy, the liquid will turn into vapor.
B.In the water cycle, evaporation occurs when sunlight warms the surface of the water. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas. Once evaporated, a molecule of water vapor spends about ten days in the air.
D. The surface area affects evaporation because if more area is exposed to air, allowing water molecules acquire more heat energy from the surroundings. Due to the increased heat energy (kinetic energy), there is more rapid movement of the water molecules which helps them to overcome the force of attraction and evaporate.
