Energy Release | MCQs

Explanation

Nuclear energy is the energy released from the nucleus of an atom, either through fission (splitting of atoms) or fusion (combination of atoms).

This energy is released in the form of heat and radiation, and is harnessed in nuclear power plants to generate electricity.

Key Points:

• Solar energy is energy from the sun
• Geothermal energy is energy from the Earth's internal heat
• Tidal energy is energy from ocean tides

Explanation

• When fuel is burned, carbon dioxide gas (CO₂) is primarily produced.
• The combustion of fuel, particularly hydrocarbons, typically results in the formation of carbon dioxide and water vapor (H₂O).

Explanation

• When oil is burnt, it undergoes combustion, a chemical reaction that releases energy in the form of heat and light.
• It produces carbon dioxide (CO2) and water (H2O) as byproducts.
• The energy released can be used to power vehicles, generate electricity, or provide warmth.
