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 (
Common examples include tea kettles, watering cans, water towers (plumbing systems), and locks for ships. 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 In communicating vessels of any shape, a stationary
✅
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). For the liquid to be at rest, the
The surfaces settle at the same horizontal level, regardless of the vessels' shapes or widths.
Here are the typical questions and answers found at the end of Paragraph 23:
