Solve your doubts! Why is it that when you blow air, if you open your mouth. It’s hot air, and if you pout your lips, it’s cold air?
Have you ever noticed that when we blow air out of our mouths. If we open our mouths wide, the air that comes out feels warm, but if we wrap our mouths into the คาสิโนออนไลน์ UFABET ฝากถอนรวดเร็ว เริ่มต้นเล่นง่าย shape of a penis, the air that comes out is noticeably colder? There is an interesting explanation in physics and thermodynamics.
Today we have collected information to answer our friends’ doubts: Why when blowing air, if you open your mouth, it’s hot air, but if you pout your lips, it’s cold air. What’s the reason? Even though we blow air out of our mouths, it’s the same.

Hot wind when opening the mouth – caused by internal body temperature
When we open our mouth wide and blow air out, the air that comes out will be close to the temperature inside our body, which is around 36-37°C, making it feel like warm air or sometimes it may feel hot depending on the temperature of the surrounding environment. In addition, the air coming out of the wide mouth will have low pressure and move slowly, causing the temperature of the air not to drop much.
Cool breeze when pouting – the mechanism of air expansion
Conversely, when we purse our lips into a penis shape, the air coming out is forced through a narrower opening, causing the air to move faster and causing air expansion, which is the same principle that works when a spray or fan works. The faster moving air draws heat energy away from our skin faster, making us feel cooler.
Physics Principle: Bernoulli’s Principle
This phenomenon can be explained by Bernoulli’s Law, which states that as air flows faster, its pressure decreases and its temperature decreases. This is why when we pout, the air that comes out feels colder than usual.
