Correct answer: C. chemical reaction

  • A. nuclear reaction
  • B. kinetic reaction
  • C. chemical reaction
  • D. potential reaction

Explanation

The burning of coal, wood, or natural gas and the release of heat and light energy into the air is a combustion process. Combustion is a chemical reaction in which a fuel (such as coal, wood, or natural gas) reacts with oxygen from the air to produce heat, light, and various combustion byproducts, including carbon dioxide and water vapor. This process is commonly used for heating, electricity generation, and various industrial processes.

About Work and Energy

Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.
