Yes it will
The hydrometer will float higher in glycerin than in gasoline because glycerin is denser than gasoline. The level to which the hydrometer floats indicates the density of the liquid it is submerged in.
Glycerin
A thermohydrometer is actually a regular hydrometer that has a thermometer inside the float section. It is very similar to the regular hydrometer.
A hydrometer will float higher in saltwater than in freshwater because saltwater is denser, providing more buoyant force.
The hydrometer will float higher in salt water because salt water is denser than fresh air. The buoyant force acting on the hydrometer is determined by the density of the fluid it is placed in, so it will float higher in salt water compared to fresh air.
Otto Hilgard Tittmann has written: 'On the reduction of hydrometer observations of salt water densities' -- subject(s): Seawater, Density, Hydrometer
a Hydrometer is used to measure the density of a solution, by the use of a scaled float. typically it is used for battery acid.
Seawater dissolves more than fresh water because of the salinity in the water.
A hydrometer consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float upright. Mercury has a higher density, thus a lower volume for the same weight than lead. It is a toxic liquid metal, but also more dangerous and difficult to clear up the mess when a glass hydrometer is broken
No. They are microscopic plants that float freely in seawater.
The lower end of a hydrometer is filled with mercury or lead because these heavy metals have a high density. This allows the hydrometer to float vertically in a liquid and provide accurate measurements of its specific gravity or density. The heavy metal helps to counterbalance the weight of the stem and bulb of the hydrometer.
probally fresh because no salt in mouth or eyes addition: it is easier to float/swim in seawater since seawater is denser than fresh water.
