It is used to find the volume of liquids and non-dissolvable solids. The level of liquids in the cylinder is marked to find the volume. In order to read the volume correctly, the cylinder must be placed on a horizontal surface and the eye shall be kept in level with meniscus of water surface. The meniscus is the top level of the liquid surface. Water in the cylinder curves downward and its surface is called concave surface. The reading is taken corresponding to the bottom edge of the surface. The mercury in the cylinder curves upward. Its surface is convex and the reading is taken corresponding to the top edge. The cylinder can be used to find the volume of solids. **Displacement Can Method: This method is used to measure the volume of solid objects that can not fit into a measuring cylinder. **Steps to Measure Volume Using a Displacement Can 1. Place the displacement can on a flat surface. 2. Pour water in it until it starts overflowing from the side opening. 3. Tie a thread to the solid body and lower it gently into the displacement can. 4. The object displaces water which overflows through the side opening. 5. Collect the overflowed water in a beaker. 6. Measure the volume of water by measuring cylinder—this is the volume of the solid object. **************************************** Related searches: class 9th physics new book, 9th class physics, 9th class physics new book 2025, new syllabus 2025 9th class, 9th class physics 2025 new book, 9th class physics new syllabus 2025, 9th class physics new book 2025 introduction, physics 9th class new book, class 9 physics lectures Ch 1, class 9th physics book lectures, 9th class physics new book, class 9 physics questions, 9th class physics notes, #9thClassPhysics #9thPhysics2025 #9thNewSyllabus #9thPhysicsNewSyllabus #ExamPreparation
