Question: 1 / 400

Which of the following increases evaporation?

Colder temperatures

Moist air

Warmer wet materials

Warmer wet materials increase evaporation because the process of evaporation is directly affected by temperature. When materials are warmer, their molecules have more energy, which enables them to transition from a liquid state to a vapor state more readily. This increased energy level leads to a higher rate of evaporation as the moisture in the materials can escape into the air faster.

In contrast, colder temperatures tend to slow down the movement of water molecules, making it more challenging for them to evaporate. Moist air also hinders evaporation because the air is already saturated with water vapor, reducing the capacity for additional moisture to enter the air. Stagnant air poses a similar issue; without movement, moisture that has evaporated tends to remain in the vicinity of the wet material, thereby limiting the overall evaporation process.
