Step 1
Which one of the following instruments can be used to measure the density of a liquid?
Answer
Among the instruments listed, the hydrometer is the correct choice for measuring the density of a liquid.
Explanation
-
Hydrometer: This device is specifically designed to measure the density (or specific gravity) of liquids. It floats in the liquid, and the level to which it sinks indicates the density.
-
Barometer: This instrument measures atmospheric pressure and is not suitable for measuring the density of a liquid.
-
Thermometer: While it measures temperature, it does not provide information about the density of a liquid.
Thus, the answer is the hydrometer.
