Question

Identify forms of energy produced by a crackling campfire.

Answer 1

1. As we know that the wood burning in the fire is seen as stored energy

(which is chemical energy).

2. The stored energy is released by burning the log.

3. A chemical reaction from wood burning is called burning.

4. This chemical reaction is called inflammation and requires oxygen.

Burning converts chemical energy into kinetic energy in the form of heat.

Answer 2

The forms of energy produced by the crackling campfire are potential energy, sound energy, heat energy, and so on.

Explanation:  

• A campfire log is viewed as potential energy that has been stored (in the form of chemical energy).

• Burning logs releases stored potential energy.

• Combustion is the chemical reaction that occurs when a log is burned.

• The potential chemical energy is converted to kinetic energy in the form of heat during combustion.
• A chemical reaction occurs when oxygen in the air reacts with a source of fuel, such as wood or gasoline.
