Energy: Forms, Transformation, Transfer, and Conservation
Item RG036003: The amount of chemical energy depends on the types and number of atoms inside the battery and how they are arranged in molecules.
Many electrical devices can be powered by batteries. When a battery is connected to an electrical device and the device is turned on, chemicals inside the battery react with each other. During the reaction, the atoms that make up the molecules of the reactants rearrange to form different molecules.
What affects the amount of chemical energy a battery has?
- The amount of chemical energy depends on the types and number of atoms inside the battery and how they are arranged in molecules.
- The amount of chemical energy depends only on the types and number of atoms inside the battery but not on how they are arranged in molecules.
- The amount of chemical energy depends on how the atoms are arranged in molecules but not on the types and number of atoms inside the battery.
- The amount of chemical energy depends on neither how the atoms are arranged in molecules nor on the types and number of atoms inside of the battery.
