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 (
✅
If you pour liquids with different densities (like water and oil) into the vessels, the heights will be different. The liquid with the lower density will have a higher column, following the formula: voprosy paragraf23 avtor peryshkin 7 klass
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
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 In the 7th-grade physics textbook by , Paragraph
). 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
Common examples include tea kettles, watering cans, water towers (plumbing systems), and locks for ships.
