When heated, part of the air is released in the form of bubbles that form on the surface of solid particles. Liquid evaporates into these bubbles. Liquid vapors inside the bubbles are saturated. With an increase in temperature, the pressure of saturated vapor increases, and the bubbles become larger. With an increase in the volume of the bubbles, the Archimedean force acting on them increases. It pushes bubbles out of the water and the bubbles float up. Usually, when the bubble breaks off, it leaves a small embryo in its place, which expands again, and so on. As the bubble approaches the surface, the volume of the bubbles increases sharply. They burst on the surface of the water. The water vapor in them escapes into the atmosphere – the water boils.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
