Discover why air feels cold when blown through tight lips and warm when blown through a wide open mouth in this engaging explanation for young minds.
Hey there! Let's learn why the air feels cold or warm when we blow it out of our mouths. It’s all about how we make the air move!
When you blow air out through tight lips, like making a small whistle, the air comes out really fast. Because it's moving quickly, it can make you feel a little chilly, like a cool breeze. This is because fast-moving air can take away some heat from your skin, making it feel cold.
On the other hand, when you blow air out of a widely open mouth, the air comes out slower and spreads out more. Since it’s not moving as fast, it doesn’t take away heat from your skin as much, making that air feel warm to you.
So, fast air = cool feeling and slow air = warm feeling. It's like riding a bicycle: when you go really fast, the wind feels cool, but when you go slowly, it feels nice and warm! That’s why blowing through tight lips feels colder than blowing through a wide open mouth. Isn’t that cool?
