A hydrometer is an instrument specifically used to measure what property of a liquid?

Explanation

A hydrometer is an instrument used to measure the density, or specific gravity, of a liquid, typically working by floating in the liquid and using a calibrated scale to indicate how far the instrument sinks, since denser liquids provide more buoyant support and cause the hydrometer to float higher. This tool has practical applications ranging from checking the state of charge in a car battery by measuring the density of its acid solution, to measuring alcohol content during the brewing or winemaking process. The specific design and calibration of a hydrometer can vary somewhat depending on its intended specific application. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
