How is density used to determine if your car battery is good?
ShirleyVelardefb1755
The electrolyte in a car battery is sulfuric acid, diluted with water. The density of the acid when fully charged is 1.265g/cm3. The chemical process, as the battery is discharged, makes the acid weaker and it becomes less dense. Down to 1.120g/cm3 when below 11volts.
Checking the acid density will give you an idea of the state of charge.
There are 6 cells in a 12v car battery. The charge of each cell should be the same. If the density is significantly different between cells, then that would indicate a fault in that cell and the battery is useless. Faulty cells may have distorted and shorted plates which would stop it being charged and show up with a different density than the other cells.

∙ 9y agoDensity is used to determine if car battery is good because if the battery is very dense it conveys that it has a significant level of power.

Density is used to determine all what except what?
Density can be used to determine the mass and the volume of a given solid.
When would it be appropriate to test density?
Density can be used to determine buoyancy. To find out of something will float or sink, density is a good way to make a prediction.
Which set of equipment would be most useful to determine the density of a liquid?
The instrument used to measure the density of a liquid is a hydrometer. These are often made for specific purposes, because the density of a given liquid may not vary much. Milk hydrometers are used to estimate the creaminess of raw milk. A battery hydrometer is used on your car battery, for the density of the sulphuric acid varies with the amount of lead dissolved, which indicates the state to which the battery is charged.
What scale is used to determine an earthquakes density?
The Richter Scale is used to determine the earthquake density. The scale is measured from low as 1 to high as 10.
What item of test equipment would be used to check the state of a non sealed battery?
A battery hydrometer which measures the specific gravity (relative density) of liquids, to determine the concentration of sulfuric acid in each cell.
What is the measuring tool for density?
A hydrometer is a special device used to determine the density of a liquid.
What is measuring tool for density?
A hydrometer is a special device used to determine the density of a liquid.
What is a hydrogrometer?
An instrument for measuring the Density of a liquid. The density of the Acid in a car Battery, changes as the stored electrici charge in the battery, is used to power things. A Hydrometer is commonly used to measure the Acid Density in Lead/Acid car batteries. The result of the Hydrometer reading let's you know how much electric charge is left in the battery. It is most commonly used to find out whether or not, the battery is old and depleted, or still in good condition. Go to Wikipedia to find out what a Hydrometer looks like.
What metal used in battery is low density?
You think to lithium (Li).
What test is used to determine a mineral based on its density in comparison to the density of water?
specific gravity test
Why do scientist measure mass and volume?
So they can determine the density of a substance. Density = mass/volume. Density can be used to identify a substance.
Flotation is a method used by scientists to determine what of a particle of glass?
Density
