Cara and violet are camping with her family. They are roasting marshmallows over a campfire. What types of energy released by the campfire a. Nuclear energy and electrical energy. B. Mechanical energy and magnetic energy. C. Heat, energy and light energy. D. Chemical energy and sound energy.
The correct answer is C. Heat energy and light energy. In a campfire, the energy released is primarily in the form of heat, which is produced by the combustion of the fuel (such as wood or coal). Light energy is also released as the fire emits a glow.
The types of energy released by the campfire can be determined by understanding the process of burning wood. When wood burns, the energy transformations occur as follows:
First, when the wood is heated by the campfire, the heat energy from the fire causes the molecules in the wood to vibrate more rapidly. This increases the temperature of the wood and starts a chemical reaction called combustion.
During combustion, the chemical energy stored in the wood is released as heat energy. This is the primary energy form being released by the campfire, as indicated by the rising flames and the warmth you feel when standing near the fire.
Additionally, the combustion of wood also releases light energy in the form of glowing embers and flames. This occurs because the high temperature of the fire causes the wood particles to emit light.
Therefore, the correct answer is C. Heat energy and light energy are the types of energy released by the campfire.
