Question

Fuel used in thermal power plants is

• A. water
• B. uranium
• C. biomass
• D. fossil fuels

Answer 1

The correct option is D

fossil fuels

The explanation for the correct answer:-

Option (D) fossil fuels:

1. Substances like coal, petroleum, or natural gases are commonly called fossil fuels.
2. At the thermal power plants, fossil fuels are used to heat the water in order to form the steam which powers the turbine to generate electrical energy.
3. As they produce a large amount of energy, fossil fuels are used in thermal power plants.

The explanation for incorrect answers:-

Option (A) water:

1. Water is used in hydropower plants not in thermal power plants.
2. There the force of falling water is used in order to rotate the turbines to generate electricity.

Option (B) uranium:

1. Uranium is a very radioactive element.
2. As a result it is used in nuclear power plants instead of thermal power plants.

Option (C) biomass:

1. Biomass is used in biomass-powered plants.
2. There, biomass such as organic waste and woods are burnt to generate heat that powers the turbine to rotate and generate electricity.

Therefore, option (D) fossil fuels are the correct option.
