Particle Motion

For simplicity's sake, we played with simulations on Thursday, I think. We had done quite a few of the simulations, so I'll do a brief summary on each one and basically what I learned from the experience. The first was predicting where the red particle will go among a group of blue particles and I made the reasonable guess that it would flow with the other particles, but it was far too unpredictable. Then we were told to think back to the Febreze experiment we did in class. What did the blue particles represent and what did the red one represent? Well obviously the blue was the air, because there was an abundance of them in the beginning and the red the Febreze as it flowed through the room. The next one was asking for the behaviors of molecules in a gas. Well, to put it simply, they were completely random. Their speed varied between the particles, they moved everywhere with no specific direction, and how when they collided with each other or the wall, they transferred energy, which gave them a boost of speed. However, no energy was gained during the process. Then, we were asked how temperature affects the speed of particles, which was simple enough. The hotter the temperature was the faster the particles moved, because the heat actually transferred its energy to the particles. The last experiment we were asked to complete was the difference between Helium and Krypton gas molecules. Well, watching the simulation, it was easy to see that the red particles or Helium was definitely faster than the Krypton, but if you increase the temperature for only Krypton then they would be moving at the same speed. I learned a lot through the simulations about molecules, energy transfers, temperature, etc. to say the least.
