Fluid at rest: WAEC Physics Past Questions and Answers
What the WAEC syllabus covers in Fluid at rest
Our summary: Density, pressure in liquids and gases, and why objects float or sink.
- Volume, density and relative density (Experimental determination for solids and liquids.)
- Pressure in fluids (Concept and definition of pressure. Pascal's principle, application of principle to hydraulic press and car brakes. Dependence of pressure on the depth of a point below a liquid surface. Atmospheric pressure. Simple barometer, manometer, siphon, syringe and pump. Determination of the relative density of liquids with U-tube and Hare's apparatus.)
- Equilibrium of bodies (Identification of the forces acting on a body partially or completely immersed in a fluid.)
- Archimedes' principle (Use of the principle to determine the relative densities of solids and liquids.)
- Law of flotation (Establishing the conditions for a body to float in a fluid. Applications in hydrometer, balloons, boats, ships, submarines etc.)
