Rainwater is indeed distilled water as it forms from the natural distillation process that occurs in the atmosphere. In fact, rainwater is one of the purest forms of water that we can find in nature. Here are some key points to consider:
When the sun heats up the earth, water from oceans, lakes and other bodies of water evaporate into the air as water vapor.
This water vapor rises up into the atmosphere where it condenses to form clouds.
As the clouds continue to grow and collect more water vapor, they eventually become heavy enough to release their moisture as precipitation, which falls to the ground as rain, sleet, or snow.
Since the water that forms clouds is pure and clean, so too is the water that falls as precipitation.
However, as rainwater falls from the sky, it may collect various impurities such as pollutants and dust particles that are present in the air. Because of this, it is recommended to collect and treat rainwater before drinking it.
Overall, rainwater is indeed distilled water, but it is important to remember that it can pick up pollutants and contaminants as it falls from the sky. Therefore, it is important to take precautions before consuming it.
