These are vessels that are connected at the bottom, allowing liquid to flow freely from one to another (e.g., a teapot and its spout).
In communicating vessels of any shape, a stationary liquid of the same density will always settle at the same horizontal level. This happens because the pressure at any given depth in a liquid depends only on the height of the liquid column ( voprosy paragraf23 avtor peryshkin 7 klass
). For the liquid to be at rest, the pressure at the bottom must be equal, meaning the heights must be equal. Questions for Self-Check These are vessels that are connected at the
The surfaces settle at the same horizontal level, regardless of the vessels' shapes or widths. For the liquid to be at rest, the
Common examples include tea kettles, watering cans, water towers (plumbing systems), and locks for ships.
Here are the typical questions and answers found at the end of Paragraph 23:
In the 7th-grade physics textbook by , Paragraph 23 focuses on Communicating Vessels (Сообщающиеся сосуды). This topic explores how liquids behave in connected containers. Key Concept: The Law of Communicating Vessels
