Glycerin
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.
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.
As salinity increases, hydrometer readings also increase. This is because a hydrometer measures the density of a liquid, and higher salinity results in a denser solution due to the dissolved salts. Therefore, as more salt is added to the water, the hydrometer will float higher, indicating a greater salinity level.
Yes it will
A high reading on a hydrometer typically indicates a higher concentration of solutes or particles in the liquid being measured, which can include sugar in a liquid such as syrup, honey, or wine. This higher concentration leads to a greater density of the liquid, causing the hydrometer to float higher than it would in pure 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
A thermohydrometer is actually a regular hydrometer that has a thermometer inside the float section. It is very similar to the regular hydrometer.
No, a coin can not float on gasoline.
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.
If the density of the ball bearing is less than the density of glycerine oil, the ball bearing will float on the surface of the glycerine oil. Objects with lower density than a liquid will float on that liquid due to buoyancy force.
If the density of a ball bearing is less than the density of glycerine oil, the ball bearing will float when placed in glycerine oil. This is because objects with lower density than the fluid they are placed in tend to float.
