Answer:
A triple beam balance measures 'mass'(a property of matter) in gram.
Step-by-step explanation:
Properties of matter are measurable traits like colour, mass, length, breadth, odour, density, temperature, malleability, melting point etc. Triple beam balance is an instrument used to measure mass of an object (mass of an object is the amount of matter contained in the object).
It is called triple beam balance because it has three beams that allow one to move objects of known masses along the beam. It measures mass precisely. The instrument had reading error of +/- 0.05grams. It contain three beams. The front beam is the smallest, the middle beam has the largest size while the end beam is the medium beam size.
