The article talks about what condensation is, which causes a similar physical process, and where it can be seen in everyday life.

Physics is one of the most important discipline for humanity. Of course, any follower considers such “his” science, but nevertheless, it was physics, along with other natural technical sciences, that allowed at least a little, but to understand the structure of our world. At all times, there were those who were not satisfied with the biblical description of the Universe and nature as a whole, and they, as pioneers, sought to figure out the situation on their own, as, for example, Mikhailo Lomonosov himself.
Unfortunately, with the popularization of physics, things are not so simple, but there are certain successes if we recall the "Entertaining Physics" by Perelman and a number of scientific works by Stephen Hawking.
And physics is interesting in that there are many processes happening around us every second that we are used to and do not pay attention to, and they are quite interesting from a scientific point of view, for example, such a phenomenon as condensation. So what is condensation? This we will understand.
Definition
If we turn to the encyclopedia, then, according to it, condensation is the transition of a substance from gaseous to liquid or solid. Simply put, this is the process of turning steam into something else, such as a liquid. At first glance, everything is quite simple, we are all used to the fact that the vapor in the room gradually precipitates in the form of water droplets on objects, and this is so. So now we know what condensation is. However, where else does such a phenomenon occur, and how is it useful?
Rain
Talking about such a physical phenomenon, one can not help but remember the rain. Indeed, it is thanks to the presence of liquid water on Earth that life was born in general. And no less important is its cycle in nature. For example, there is also water on Venus, but alas, only in the form of steam, which never reaches a hot surface and simply covers the planet with dense clouds that cause a greenhouse effect and increase the temperature even more.
Fortunately, in the case of our planet, everything is different: we have a normal water cycle, thanks to which its balance is maintained. So what is condensation, and what does it have to do with rain?
In fact, everything is simple, just remember the school course in natural history. Liquid water gradually evaporates from the surface of the earth, and then rises in the form of steam. And here the fun begins: the higher the lower the temperature, and the warm steam gradually cools, returning to its original state - water. And then this water in the form of rain spills back to the ground to evaporate and repeat this cycle. So now we know what condensation is in physics. But where else at the household level can this process be observed?
Window
In the cold season, moisture can be seen on the inside of the windows - this is also an example of condensation. This occurs, as a rule, due to the temperature difference outside and inside the room and due to excess humidity. By the way, precisely because of this, in the winter season, frosty patterns can be observed on window panes .
Condensation can also be noticed during cooking, when steam rises from a pot of boiling water and settles on the walls or objects with small droplets of liquid. This process is also most pronounced in the steam room of the bath: if water is poured onto a hot fireplace, it will go into a gaseous state and, as the temperature drops, will begin to condense on the walls and floor.
So now we know what evaporation and condensation are. By the way, according to the law of conservation of matter and energy, exactly as much steam as evaporated will go back into the liquid state.
