Which energy conversion occurs in a battery-powered flashlight?

chemical energy to mechanical energy

mechanical energy to thermal energy

electrical energy to electromagnetic energy

electrical energy to chemical energy

chemical energy to electrical energy

Explanation:

The type of energy stored in a battery is chemical energy.

A battery-powered flashlight gives light when switched-on, during this process the chemical energy stored in the battery is converted into electrical energy or light energy. When the flashlight is switched off, we convert the electrical energy back to chemical energy.

Therefore, the energy conversion that occurs in a battery-powered flashlight is chemical energy to electrical energy or electrical energy to chemical energy.
