What is triple beam balance used for?

• A. Instrument used to measure volume
• B. A device for heating substances
• C. Instrument used to measure mass
• D. A device that records time

Answer: (C)

The main idea here is measuring mass. A triple beam balance determines how much matter an object contains by comparing it to known masses. It uses three sliding weights on separate beams (hundreds, tens, and ones of grams). You place the object on the pan, balance the beam so the pointer lines up at zero, then read each beam's value and add them together to get the mass in grams. This tool specifically measures mass, not volume (which you’d measure with a graduated cylinder or ruler), time (measured with a stopwatch), or heating (which involves a heater or furnace). It’s used when you need a precise mass value for experiments.
