Determine the specific gravity of Alum by Hydrostatic balance

Determine the specific gravity of Alum by Hydrostatic balance Alum is both a specific chemical compound and a class of chemical compounds. The specific compound is the hydrated potassium aluminium sulfate (potassium alum) with the formula KAl(SO4)2·12H2O. More widely, alums are double sulphate salts, with the formula AM(SO4)2·12H2O, where A is a monovalent cation such…

Determine specific gravity of Kerosene by specific gravity bottle

Determine specific gravity of Kerosene by specific gravity bottle Two methods are commonly used for determining the specific gravities of liquids. One method uses the hydrometer, an instrument that gives a specific gravity reading directly. A second method, called the bottle method, uses a "specific-gravity bottle," , a flask made to hold a known volume…

Determination of g by Simple Pendulam

Determination of g by Simple Pendulam In physics, gravitational acceleration is the acceleration on an object caused by gravity. Neglecting friction such as air resistance, all small bodies accelerate in a gravitational field at the same rate relative to the center of mass. This equality is true regardless of the masses or compositions of the…

Determination of speed of sound by resonance air column method

The speed of sound is the distance travelled during a unit of time by a sound wave propagating through an elastic medium. In dry air at 20 °C (68 °F), the speed of sound is metres per second (1,126 ft/s). This is 1,236 kilometres per hour (768 mph), or about one kilometer in three seconds…
