Question

how does the following affect the rate of evaporation of liquids surface area and humidity ​

Answer 1

1. As surface area increases, rate of evaporation increases. So surface area is directly proportional to the rate of evaporation.

2. As humidity increases, rate of evaporation decreases. So surface area is inversely proportional to the rate of evaporation.

Hope this helps! :)

Answer 2

Answer:

SA ∝ Evaporation

Humidity ∝ 1/Evaporation

Explanation:

Evaporation is the process when a liquid is vaporized at a temperature lower than its boiling point.

(i). Surface Area: Greater the surface area, more the evaporation will be and lesser the surface area, lesser the evaporation will be. In other words, SA ∝ Evaporation.

(ii). Humidity: The moisture content in the atmosphere is known as humidity. If humidity is high, rate of evaporation will be lesser as the atmosphere already has moisture and vice-versa. This means Humidity ∝ 1/Evaporation.
