You must have seen that as soon as winter starts, steam starts coming out of our mouth. But this does not happen in summer. Whereas, be it humans or animals, the way oxygen enters their body while breathing in summer and carbon dioxide comes out when they exhale, similarly it happens in winter as well. In fact, according to science, 60 percent of the human body consists of water, so when we exhale, not only carbon dioxide comes out of our body, but some amount of water vapor also comes out along with it. When the same vapor comes out in the cold, it freezes and becomes visible to you.
In the language of science, understand why this happens
Science According to this, if we understand it, then the molecules in the gas are far apart, in the liquid a little closer and in the solid stick together. That is the state between steam, liquid and gas. If seen, when there is heat in the outside temperature and moisture comes out of the body, it remains in gaseous state only. During this, the kinetic energy of its molecules does not decrease and they remain far away. This is the reason why in summer the breath does not turn into steam or water droplets. On the other hand, when the outside temperature is low, the moisture and gas coming out of the mouth lose their kinetic energy rapidly and its molecules come closer. These molecules come close together and become steam and we can see. Not only temperature but humidity is also responsible for this. Actually, when the vapors of water present in the breath become dense, they take the form of liquid. This means that if there is more moisture in the air, then you can get a chance to see the breath, even if the weather is a bit hot. On the other hand, if the weather is dry and it is too cold, then the chances of steam coming out of the mouth will be less.
