Which energy transformation takes place when a firecracker explodes
Gravitational potential to mechanical and electromagnetic
Nuclear to magnetic and chemical
Mechanical to electromagnetic and electrical
Chemical to thermal and electromagnetic
The chemical reaction is primarily oxidation, fast burning. However electromagnetic ? Only if it sets your phone off.
Since the last choice is the only one to include "thermal", that would be my choice.
The correct answer is:
Chemical to thermal and electromagnetic.
When a firecracker explodes, it undergoes a chemical reaction that releases a large amount of energy. This chemical energy is converted into thermal energy and electromagnetic energy.
To arrive at this answer, you can follow these steps:
1. Understand the concept: Energy transformations occur when one form of energy is converted into another form. In the case of a firecracker explosion, the energy released during the chemical reaction is transformed into other energy forms.
2. Identify the initial form of energy: In this case, the firecracker stores chemical potential energy due to the chemicals within it, which have the potential to release energy during a reaction.
3. Determine the final forms of energy: When the firecracker explodes, the chemical energy is converted into thermal energy, which is the energy associated with heat. The explosion also produces electromagnetic energy in the form of sound, light, and heat.
4. Match the initial and final forms of energy: By analyzing the options provided, you can determine that the best match for the energy transformation in a firecracker explosion is "Chemical to thermal and electromagnetic."
By following these steps, you can understand the energy transformation that takes place when a firecracker explodes and arrive at the correct answer.
