Eduscope India is a leading Hare's Apparatus
Quick Answer:Hare's Apparatus is a three-limbed glass-tube instrument used to compare the densities of two liquids by measuring their suction-drawn column heights side by side.
The apparatus consists of a three-limbed glass tube mounted on a wooden stand, with a scale fitted to each of the two outer limbs so column heights can be read directly, and two sliding distance rods that can be adjusted so their lower ends just meet the liquids for an accurate reading. A rubber tube with a clip on the short centre limb is used to apply suction. With the two outer limbs placed in the liquids being compared, the same reduced pressure draws each liquid up its own tube to a height that depends on its density — the denser liquid rises less, the lighter liquid rises more — making this a simple, visual way to compare liquid densities as part of a physics practical equipment CBSE syllabus.
