Question

Clouds are made up of tiny water droplets or ice crystals floating in the air. Based on what you know about solutions, suspensions and colloids, what type of mixture do you think clouds are and why?

Answer 1

• Clouds are considered colloids.
• They consist of tiny water droplets or ice crystals (dispersed phase) evenly distributed in air (dispersion medium).
• Their particles are small enough to stay suspended without settling down.
• They also exhibit the Tyndall effect by scattering light, which is a key characteristic of colloidal systems.

Therefore, clouds are classified as colloids.
