How to describe white breath when the weather is cold

Description of exhaling white gas when the weather is cold:

1. In the cold winter, students keep exhaling "white gas" from their mouths, which is the liquefaction of water vapor; in the morning, there is snow on the grass A layer of frost is the phenomenon of condensation.

2. In the cold winter, when people breathe or talk outdoors, the breath coming out of their mouths looks like mist and is white. 3. People shout that it’s so cold while exhaling into their hands in pursuit of instant warmth. The bursts of exhaled air liquefy when exposed to cold, turning into white air visible to the naked eye. This not only makes people feel ethereal, but also reminds people that winter is really coming.

4. The reason why we can exhale "white air" from our mouths in winter is actually caused by higher temperature water vapor ejected from our mouths and turned into cold air.

5. When water vapor in the air encounters colder objects, it liquefies into tiny water droplets and floats in the air, thus the "white gas" we see appears.

6. In winter, the road freezes hard, and it is obvious that the asphalt road surface is not as elastic as it is in warm weather. The white air I exhaled was heavy, and the rough wind was carving it randomly one stroke at a time. My face and ears were numb with pain.
