Final answer:
The brilliant lights of fireworks are due to energy bursts emitted by atoms, where heat causes a chemical reaction and the atoms release light energy. Activation energy is needed to initiate this reaction, and the physics of the explosion demonstrate conservation of momentum and center of mass.
Step-by-step explanation:
Fireworks are a source of grand spectacle because of their brilliant, colored lights. These lights are essentially bursts of energy emitted by atoms within the fireworks. The cause of these bursts is related to the energy levels of atoms. When heat is applied to a firework, it triggers a chemical reaction that excites the atoms. As these atoms return to their normal state, they release energy in the form of light, resulting in the vivid colors we see during a fireworks display.
Furthermore, the concept of Activation Energy is important in understanding how fireworks function. Activation energy is the minimum amount of energy required to initiate a chemical reaction. In fireworks, the heat from a lit fuse provides the activation energy needed for the chemicals to react, leading to the eventual explosion and the spectacular display of lights.The laws of physics, specifically conservation of momentum and center of mass, are exhibited when a fireworks rocket explodes. As the rocket detonates, glowing fragments are propelled in all directions, showcasing conservation of momentum and a shifting center of mass.
