What will be the effect of surface area on the evaporation process?
Evaporation decreases with increase in surface area.
Evaporation increases with decrease in surface area.
Evaporation increases with increase in surface area.
No effect of surface area on evaporation process.
Evaporation increases with increase in surface area.
Evaporation is a surface-level phenomenon where particles at the surface of a liquid gain enough kinetic energy to escape into the gaseous state. Because it occurs only at the surface, increasing the surface area exposes more liquid molecules to the air, thereby increasing the rate of evaporation.

If you spill a cup of tea on a table, it spreads out and cools down (evaporates) very quickly because the large surface area allows many molecules to escape at once. However, the same amount of tea in a narrow cup takes much longer to evaporate because the surface area exposed to the air is limited.
RateтИЭA
where A represents the surface area exposed to the atmosphere.
According to the kinetic molecular theory, particles in a liquid have a range of kinetic energies. Particles with higher-than-average kinetic energy located at the surface can overcome the intermolecular attractive forces of the bulk liquid and transition into vapor. A larger surface area increases the number of molecules positioned at the interface, directly raising the probability of these high-energy escape events per unit of time.
Evaporation is a surface phenomenon.
Higher temperature, larger surface area, and lower humidity increase the rate of evaporation.
Wind speed also increases the rate of evaporation by carrying away vapor particles from the surface.
Spreading wet clothes to dry them faster.
Using wide plates to cool hot beverages like tea or coffee.
Option A is incorrect as it describes the inverse relationship.
Option B is incorrect as it describes the inverse relationship.
Option D is incorrect because surface area is a primary factor influencing evaporation.
C is correct тАФ Evaporation is a surface-dependent process, so increasing the surface area provides more space for molecules to escape, thereby increasing the rate of evaporation.
Remember that evaporation is a cooling process; since high-energy particles leave, the remaining liquid has lower average kinetic energy, resulting in a drop in temperature.
