Question

which of the following shows the correct sequence of energy flow, as the different types of energy are converted from one type to the other in each stage of the process? coal coal - fired power plant power tower radio electrical energy - thermal energy - chemical potential energy - sound energy chemical potential energy - electrical energy - thermal energy - sound energy chemical potential energy - thermal energy - electrical energy - sound energy thermal energy - chemical potential energy - electrical energy - sound energy

Explanation:

Step1: Analyze energy in coal

Coal has chemical - potential energy stored in its chemical bonds.

Step2: Analyze energy conversion in power - plant

In a coal - fired power plant, the chemical - potential energy of coal is converted to thermal energy by burning.

Step3: Analyze energy conversion in power - generation

The thermal energy is then used to generate electrical energy.

Step4: Analyze energy conversion in radio

The electrical energy is used by the radio to produce sound energy.

Answer:

Chemical potential energy → Thermal energy → Electrical energy → Sound energy
