The life of the battery. You never have to change it.
Maybe you'd like to explain what you mean. I can't believe you actually want your headlights to remain on all the time - you'd flatten the battery.
Ruin the battery.
The function of the Magic Eye® state of charge battery indicator is based on the specific gravity of the sulfuric acid or electrolyte. When a battery is charging, the change in the density of the acid is a little delayed as compared to the actual state of charge of the battery. However, the battery indicator should show green once the battery is back to 100% state of charge. There may be several reasons as to why it is not showing green: 1. If the battery was allowed to remain in the dis-charged state for a great length of time, the battery may in fact be bad and the battery indicator will not show green because the electrolyte has not reached the proper specific gravity. The specific gravity of the electrolyte is the most accuarate method of measuring state of charge. 2. The acid in the battery is "stratified" meaning that the heavier acid has sunk to the bottom and the lighter water is floating near the top. This happens with batteries that have sat for a long time in the discharged state. Normally, re-charging will stir the electrolyte make it more homogenious. 3. There may be a small piece of battery separator material preventing the green ball from floating up. The best thing to do is gently rock the battery back and forth. This will mix the electrolyte and will most likely free the green ball to float up "IF" the specific gravity of the acid is dense enough. Keep in mind that even though the Magic Eye®is located in only 1 of 6 cells, testing conducted by a major OE car company proved that the battery indicator accurately indicates the state of charge of the entire battery.
No, Terminal voltage of a battery can't be zero. For example, if my mobile's battery is at low charge. It is showing only one point of charge on screen, but there will be no fluctuation on its screen, all the other features like audio, video, display will remain same unless it will become fully out of charge. Charge could be zero but the voltage can't be zero. Well, actually the terminal voltage of a battery can be zero, but only when the battery is totally dead and unable to take a charge (if it was a rechargeable type battery). At this point it must be disposed of. One exception is wet cell batteries (like lead acid), if the liquid electrolyte is removed the terminal voltage goes to zero but the battery is still good and can be restored to normal operation by refilling it with electrolyte. In fact wet cell batteries are often sold fully charged but with no electrolyte and their terminal voltage is thus zero on the store shelf until the salesman fills them with electrolyte.
To reset an alarm for a 94 Corolla after changing the battery, place the key in the ignition and turn it slightly. Let it remain in that position for several minutes before starting the car.
Methanol is a weak electrolyte because it does not dissociate completely into ions in solution. While a small portion of methanol molecules may break apart into ions, most remain intact as neutral molecules. This results in a low concentration of ions in solution, making it a weak electrolyte.
Melting snowflakes is a physical change, not a chemical change. The water molecules in the snowflake remain the same chemical composition before and after melting, they just change from a solid to a liquid state.
Washing shoes is a physical change because the composition and chemical structure of the shoes remain the same before and after washing. The change is reversible and does not alter the material at a molecular level.
You cannot track anyone from the mail. The email firstly cannot be changed after creation. You have to remain with the same address as before.
Thawing of meat is a physical change because the change in state from frozen to liquid does not alter the chemical composition of the meat itself. The molecules in the meat remain the same before and after thawing.
Substance in the material Remain the same
In a chemical change, the particles that change are atoms and molecules. Bonds between atoms break and form new connections, leading to the formation of different substances with unique chemical properties. The number and type of atoms remain the same before and after the reaction, but their arrangement and bonding change.
