Evaporation increases with:a)Increases in the area of exposureb)Decrea...
Explanation:
Increases in the area of exposure:
- Evaporation is the process by which water changes from liquid to vapor.
- The rate of evaporation is directly proportional to the surface area of exposure.
- When the area of exposure is increased, more water molecules are able to escape into the air as vapor, leading to higher evaporation rates.
- For example, a shallow pan of water will evaporate faster than a cup of water due to the larger surface area.
Decreases in the area of exposure:
- On the other hand, if the area of exposure is decreased, there will be fewer water molecules able to escape into the air.
- This will result in slower evaporation rates, as there is less surface area for the water molecules to evaporate from.
Increases in the amount of water:
- While the amount of water present can affect the overall evaporation rate, the key factor in this question is the area of exposure.
- Even if there is a larger amount of water present, if the area of exposure is limited, the evaporation rate will still be slower compared to a smaller amount of water with a larger area of exposure.
Decreases in the temperature:
- Temperature does have an impact on evaporation rates, as higher temperatures can increase the kinetic energy of water molecules, leading to faster evaporation.
- However, in the context of this question, the focus is on the area of exposure rather than temperature.
