While not 100% pure, a cloud droplet is essentially made up of pure water, despite needing a particle to form.
Even though every cloud droplet requires a tiny particle, known as a condensation nucleus (a speck of dirt, dust, or salt crystal), to form, the resulting cloud droplet is still primarily pure water. So, while not absolutely pure, clouds are predominantly water.
Here's a breakdown:
- Condensation Nuclei: These are essential for cloud formation. Without them, water vapor would have a harder time condensing into liquid droplets.
- Water Dominance: Despite the presence of these particles, the vast majority of a cloud droplet's composition is water.
Therefore, clouds can be considered highly pure, consisting mainly of water despite the initial presence of a condensation nucleus.
