In a power plant based on natural gas, what creates the high-temperature, high-pressure gas that runs the turbine?
AFission of plutonium in a core
BCombustion of gas in hot air
CBoiling of water by mirrors
DFalling of water from a dam
Answer & Solution
Correct answer: B. Combustion of gas in hot air
1. A compressor forces pressurised air into the combustion chamber.
2. Natural gas burns in this air inside the chamber.
3. This produces gas at very high temperature and pressure, which runs the turbine.
4. Fission (option A) belongs to nuclear plants, so it is ruled out.
