1. Electrical energy flows through the power cord into your device. There, it's converted into potential energy that's stored in the battery. The potential energy gets converted back to electrical energy to power your device.
2. Electrical energy is converted into mechanical energy by a motor. The motor drives a compressor, and this compresses and heats the refrigerant. Mechanical energy is converted into thermal energy in this process.
3. Overall reaction is from chemical energy to sound energy. Battery in radio is comprised of chemical energy. When a radio is turned on by inserting a battery, the chemical energy of the battery is converted into electrical energy. Further electrical energy is converted into sound and heat energy.
