Car battery

Explanation: Remote -control battery, flashlight battery and AA battery are all examples of dry cell. In a dry cell, the electrolyte is absorbed in a solid form and because o this no leakage takes place.

Car battery is actually a battery which is mainly lead-acid battery. these are rechargeable batteries and perform heavy duties. Lead-acid battery have lead and lead oxide plates immersed in sulfuric acid(electrolyte). Oxidation and reduction of lead takes place which creates a potential difference and the electric energy is generated. These batteries could be recharged when they gets discharged and could be used for longer.

a polar bond is formed when electrons are shared unevenly between atoms

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
