Question

this diagram shows key components in a natural gas power plant. use an energy transfer model to track how energy transfers within the system.

Explanation:

Step1: Identify initial energy form

The natural - gas has chemical energy.

Step2: First energy conversion

When natural gas is burned, chemical energy is converted to heat energy to boil water and create steam.

Step3: Second energy conversion

The steam causes the turbine to rotate, converting heat energy to mechanical energy.

Step4: Third energy conversion

The rotating turbine is connected to a generator, converting mechanical energy to electrical energy.

Step5: Final energy transfer

The electrical energy is transferred through wires for distribution.

Answer:

Chemical energy in natural gas → Heat energy from burning gas to make steam → Mechanical energy of turbine rotation → Electrical energy in generator → Electrical energy distribution through wires
