Main idea: Buoyancy of an object is determined by properties of the object as well as properties of the fluid surrounding it. density=mass/volume More dense at bottom The result of pressure exerted equally in all horizontal directions by water. Pressure at bottom greater than at top A substance that is able to take the shape of any container that holds it. If a density is less than that of water (or the liquid it is floating in) acts against buoyant force A buoyant force on an object is equal

March 4‚ 2010 Egg Buoyancy and Density: Can you make an egg float by changing the density of water? If you put an egg in tap water‚ it will sink to the bottom. If you add enough salt‚ the egg will float to the surface. Density is the mass or volume of an object. It’s easier to think of it as the thickness of the object. Buoyancy is the force that allows an object to float. I performed a fun experiment to see how increasing density of water could make an egg float or submerge.

Archimedes’ Principle The buoyant force on a submerged object is equal to the weight of the fluid displaced. This principle is useful for determining the volume and therefore the density of an irregularly shaped object by measuring its mass in air and its effective mass when submerged in water (density = 1 gram per cubic centimeter). This effective mass under water will be its actual mass minus the mass of the fluid displaced. The difference between the real and effective mass therefore

Blaise Pascal duplicated Torricelli’s barometer using a liquid of density 984 kg/m3 as the working liquid (Fig. 3). What was the height h of the liquid column for normal atmospheric pressure? 10.5 m 5. A frog in a hemispherical pod finds that he just floats without sinking in a fluid of density 1.35 g/cm3.
