Why Can We See Our Breath In The Cold?

The video explains why we see our breath on cold days, attributing it to the rapid change in dew point, where warm, moist air from our lungs condenses into visible droplets when it hits cold air. This process is similar to how fog and clouds form. The video also discusses the role of condensation nuclei, tiny particles in our breath, which help water vapor condense. Additionally, it highlights scientific research into analyzing exhaled breath condensate for detecting air pollutants and respiratory illnesses.
