Question

how does each of the following affect the rate of evaporation of a liquid in an open dish? (a) intermolecular forces as the strength of the intermolecular forces increases, the rate of evaporation decreases . (b) temperature as temperature increases, the rate of evaporation increases . (c) surface area as surface area increases, the rate of evaporation stays the same

Answer 1

The rate of evaporation decreases with stronger intermolecular forces, increases with higher temperatures, and generally increases with larger surface area.

Step-by-step explanation:

The rate of evaporation of a liquid in an open dish is affected by several factors:

• (a) Intermolecular forces: As the strength of intermolecular forces increases, the rate of evaporation decreases. Stronger forces mean more energy is required for molecules to escape into a gas state.
• (b) Temperature: As the temperature increases, the average kinetic energy of the molecules also increases. This means that more molecules have enough energy to overcome the intermolecular forces and evaporate.
• (c) Surface area: While not explicitly mentioned in the reference information provided, generally, as the surface area of the liquid increases, the rate of evaporation also increases, because more molecules are exposed to the possibility of escaping into the gas phase.

These concepts demonstrate the dynamic relationship between intermolecular forces, temperature, surface area, and evaporation rate.
