Why steam comes out of the mouth in winter? Know the reason behind this here

You must have often seen that steam comes out of your mouth during the winter season. This happens while exhaling through the mouth. But sometimes such an incident happens in the summer season also. But, here we are going to tell you why steam comes out of our mouth.


This is the reason for the steam coming out of the mouth in cold.

The average human body temperature is 18.6 degrees Fahrenheit. While exhaling in winter, this heat attaches to it and comes out. As hot air leaves the body and reaches the cooler environment, it starts evaporating. For this reason, in winter, steam is seen coming out of the mouth while exhaling. According to science, where the temperature drops to zero or below, the steam coming out of the mouth starts turning into ice.

Why doesn't steam come out of the mouth in summer?

Actually, in summer the outside temperature is not lower than the body temperature. In such a situation, when moisture comes out from the body, the kinetic energy of its molecules does not decrease and they stay away from each other. That is, the moisture remains in the gaseous state. This is the reason why moisture does not turn into vapor or water droplets. That's why you do not notice steam coming out of your mouth in the summer season. By the way, you must have also noticed that even in winter, the environment or place where the temperature is not much lower than your body, steam does not come out of our mouth even there. Such as in closed houses or during sunlight on the roof.
