State how temperature affects evaporation.

Temperature plays a significant role in the process of evaporation. Here's how:

1. Increase in Temperature: As the temperature increases, the kinetic energy of the water molecules also increases. This means the molecules move faster. When the molecule at the surface gets enough energy, it can escape and turn into a gas. Therefore, higher temperatures lead to increased rates of evaporation.

2. Decrease in Temperature: Conversely, when the temperature decreases, the kinetic energy of the water molecules decreases as well. The molecules move slower and fewer of them have the energy to escape the surface and become a gas. Therefore, lower temperatures lead to decreased rates of evaporation.

3. Constant Temperature: At a constant temperature, evaporation can still occur. This is because there are always some molecules with enough energy to escape into the gas phase. However, the rate of evaporation will be constant and not increase or decrease.

In summary, temperature affects evaporation by controlling the kinetic energy of the water molecules. The higher the temperature, the faster the evaporation, and vice versa.
