Problem:

which sequence of energy transformation best describes what happens when you switch on your battery run radio? ​

The battery have a stored chemical energy which can be converted into some other forms of energy. When you turn-on the radio, chemical energy of the radio converted into electrical energy as current flows in the wire. Electrical energy converted to sound energy using the speaker. As you continue to use the radio, you will observed that the battery and other electrical component of the radio heat-up, which means thermal energy is also produce. If you observed a light in a certain part of the radio, it means electrical energy is converted to light energy.

                                     Thermal energy

                                           ↑

chemical energy → electrical energy → sound energy

            ↓                            ↓

Thermal energy           Light energy  → thermal energy

A) Microwave Oven is a machine which change electrical energy to heat energy...
