A barometer measures atmospheric pressure to determine weather conditions, while a hydrometer measures the specific gravity of liquids to assess their density or concentration. In summary, a barometer is used for weather forecasting, while a hydrometer is used for analyzing liquid properties.

Is hydrometer a weather instrument?

Yes it is.as the barometer calculates the temperature so their working together''according RICHARD pinciple''


How does calculated specific gravity compare to the hydrometer reading for the liquid?

The calculated specific gravity may be slightly different than the hydrometer reading. The calculated gravity is calculated using specific data while the hydrometer measures the liquid at a specific time and temperature.


How does the calculated specific gravity compare to the hydrometer reading for each liquid?

The calculated specific gravity may be slightly different than the hydrometer reading. The calculated gravity is calculated using specific data while the hydrometer measures the liquid at a specific time and temperature.


Will the hydrometer float higher in glycerin or in gasoline?

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.


What is the difference between Mercury barometer and a aneroid barometer?

their spelling is different.


Why the pycnometer method more accurate than the hydrometer method?

The pycnometer method is more accurate than the hydrometer method because it uses an analytical balance.


Will hydrometer float higher in fresh air or salt water and why?

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.


Why would a water barometer have to be 13.6 times taller than a mercury barometer?

A barometer using water,would need to be 13.6 times taller than a mercury barometer to obtain the same pressure difference. This is because mercury is 13.6 times more dense than water.


An aneroid barometer is different from a mercury barometer in that it does not contain?

An aneroid barometer does not contain mercury. Instead, it uses a small, flexible metal box called an aneroid cell to measure air pressure changes. Aneroid barometers are safer and more portable than mercury barometers.


Why is the hydrometer used to find density?

A hydrometer can be used to find the specific gravity (relative density) of a liquid by determining how much water it will displace. Various calibrations are used for different kinds of liquids.


How does a hydrometer measure density?

It measured by the density of the size from the hydrometer.


Will a hydrometer float higher in fresh or salt water?

A hydrometer will float higher in saltwater than in freshwater because saltwater is denser, providing more buoyant force.
