Water only evaporates when it reaches 100°C, right?

Water does not evaporate before reaching 100°C.

Cause of error:

Water evaporates at any temperature, but the evaporation rate is different. Evaporation refers to the process by which molecules on the surface of a liquid accelerate their irregular movement and the molecules on the surface continually escape into the surrounding space. The rate of water evaporation is related to factors such as temperature, air flow and water surface area. Although the boiling point of water is 100℃, it does not mean that water will only evaporate when it reaches 100℃, but that it evaporates most quickly at 100℃.

Factors affecting evaporation:

The rate of evaporation is affected by many factors. First of all, temperature is one of the most important factors affecting the rate of evaporation. As the temperature increases, the molecules on the surface of the liquid gagenerate more energy, thus speeding up the evaporation process. Second, the speed of airflow will also affect the speed of evaporation.

When air flows faster, molecules on the surface of the liquid escape more easily into the air, speeding up the evaporation process. In addition, the surface area of ​​the liquid is also one of the factors that affect the evaporation rate. As the surface area of ​​the liquid increases, more of the liquid surface area can come into contact with air, thereby increasing the rate of evaporation.

The impact of evaporation on nature:

1. Climate Regulation:

Evaporation is one of the important processes in climate regulation. the Earth's climate. Evaporation helps maintain Earth's water cycle by moving water from the surface and subsurface to the atmosphere and affects the pattern and frequency of precipitation. In certains regions, such as desert areas, evaporation can even be the main source of water.

2. Water Cycle:

Evaporation is an important part of the water cycle. It draws water from the surface and subsurface and releases it into the atmosphere, providing the moisture needed for cloud formation and precipitation. Without evaporation, the water cycle on Earth would be seriously affected.

3. Ecological Balance:

Evaporation also plays an important role in maintaining ecological balance. For example, many plants rely on evaporation to help water rise from the roots to the leaf surface, which is essential for the plant's growth and survival. At the same time, evaporation also affects air temperature and humidity, thereby affecting the living habits and migratory behavior of animals.

4. Shaping of the relief:

Evaporation also participatesin the process of shaping the relief. For example, in arid areas, evaporation causes salt to accumulate on the surface, forming salt marshes and salt lakes. Additionally, evaporation can cause groundwater to erode, forming caves and underground rivers.
