Question

How does each of the following affect the rate of evaporation of a liquid in an open dish?

a. intermolecular forces

b. temperature

c. surface area

Short answer

a)Intermolecular forces: Intermolecular forces act between the molecules of a substance. As the intermolecular forces increase, the rate of evaporation decreases.

b)Temperature: As temperature increases, the rate of evaporation increases.

c)Surface area: As the surface area increases, the rate of evaporation increases.

Step-by-step solution

Evaporation

Evaporation is the slow and continuous process in which a liquid changes into its vapor at all temperatures below its boiling point.

Step 2:Factors affecting the rate of evaporation

The following factors influence the rate of evaporation:

1. Intermolecular forces.
2. Temperature
3. Surface area

Explanation 

a)

Intermolecular forces: Intermolecular forces act between the molecules of a substance. As the intermolecular forces increase, the rate of evaporation decreases.

b)

Temperature: As temperature increases, the rate of evaporation increases.

c)

Surface area: As the surface area increases, the rate of evaporation increases
