4. Why do we experience cloud like smoke near our mouth while we speak during the winter season?
Answers
Answer:
Cold air causes the warm moisture in our breath to condense into tiny droplets of water that appear like a small, misty cloud
Answer:
What comes out of your mouth is not smoke, it's condensation. Whenyou blow air out of your mouth, the moisture that comes out is at your body temperature. When it hits the colder air outside, the moisture follows the laws of conversion (the laws of a substance going from a gas, to a liquid, to a solid or vice versa when the temperature reach various points, such as the freezing and the boiling point) and condenses into a liquid or freezes into a solid (depending on how cold it is outside of the body).
You feel warmer air on your hand when you blow from your mouth because the air in your body is warmed to your internal temperature. The outside of your hand is in a colder environment, so the air from your mouth feels warm compared to your hand's surroundings. Your hand feels cooler at a farther distance from your mouth due to the fact that the air from your mouth has been exposed to a cooler environment outside of the body for a longer period of time than when your hand was closer to your mouth. Since the warm air has been in a larger ammount of cool air for a longer time, the cool air cools the warm air to a temperature that is not as hot as your body temperature.
