Does Hydrometer Sink Water?

The function of the hydrometer is based on Archimedes principle that a solid suspended in a liquid will be buoyed up by a force equal to the weight of the liquid displaced. Thus, the lower the density of the substance, the lower the hydrometer will sink.

Why does my hydrometer sink?

The hydrometer has a definite mass and volume. By the principle of Archimedes, it floats when it displaces an equal mass of liquid. Since the lighter liquid has less mass per volume, a larger volume of liquid must be displaced. For the hygrometer to displace a larger volume, it sinks further.

In which liquid the hydrometer sink more?

Ranges. The hydrometer sinks deeper in low-density liquids such as kerosene, gasoline, and alcohol, and less deep in high-density liquids such as brine, milk, and acids.
