Answer the question below using your knowledge on principles of particle model of matter. You may use a separate sheet when necessary. Question: Could you explain how the particle model explains why a balloon inflates when filled with air? ter 1
Answer (1)
Answer:The particle model of matter explains the behavior of gases, including the inflation of a balloon, through the interactions and movement of particles. When air is pumped into a balloon, the air particles (mainly nitrogen and oxygen) are introduced into the confined space of the balloon.1. Movement of Particles: According to the particle model, matter is made up of tiny particles that are in constant motion. In gases, these particles move freely and rapidly. When air is added to the balloon, the air particles collide with the inner walls of the balloon.2. Increased Pressure: As more air enters the balloon, the number of particles inside increases, which leads to more frequent collisions with the balloon's walls. This increase in particle collisions raises the pressure inside the balloon.3. Expansion of the Balloon: The elasticity of the balloon material allows it to stretch as the pressure from the air particles inside pushes outward. The balloon expands because the internal pressure exceeds the external pressure, allowing it to accommodate more air.4. Dynamic Equilibrium: When the balloon is filled to a certain point, the pressure inside can reach a balance with the pressure outside, stabilizing the size of the balloon. If too much air is added, the internal pressure may become too great, potentially causing the balloon to burst.In summary, the particle model effectively describes how the behavior and movement of gas particles lead to the inflation of a balloon, illustrating key principles of gas behavior, such as pressure and volume relationships. For a more detailed understanding, you may refer to additional educational resources on the particle model and gas laws.
