Week 6 Blog

This week in chemistry we focused on particles and what affects them. We found out that particles are in motion and they go in different directions. We even found out that temperature does affect the motion of particles. The mass does stay the same for the particles but the volume increases and the density decreases. The particles never stops moving. Though in cold water particles move slower than in the warm water. The gas particles move the most out of the three substances. Gas particles are the least dense, the warmest, it's fluidity, which means the particles have a flow ability and no structure at all. It also has more range of motion and is the least viscosity, which means it has a resistance to flow. In a solid the particles are always moving never touching or ever getting away. They are also the most dense and rigid. Solid particles have a lattice, which means a consistent structure. In a liquid particles move fast, they snap like a spring and they are lattice. They have no shape because it seeks the lowest possible level pulled by gravity and turns flat. They do take the shape of the container they are in. Liquids are warmer than solids and are fluidity. Molecules can have a translational motion, a rotational motion and/or a vibrational motion. So, when we drawl particles we want to show what their motion is. for example whoosies are arrows showing the direction particles go. A vector shows if the particles have vibration or not. Earlier I mentioned how liquid and gas particles are fluidity, well we talked about some examples about fluidity in class. one was if we have to cups of tea and put lemon juice in one and honey in the other which one is more fluid. Once we discussed how thick honey was compared to lemon juice we realized that the tea with the honey was more viscous, resistance to flow. Which meant that the lemon juice was more fluid, able to flow easily. As for the affect of temperature having on the particles, we watched a lab being done on it. There were two glasses of water, one cold and one hot, and then each had food coloring poured in. The glass with the hot water the food coloring traveled through the water faster and the glass with the cold water the food coloring traveled through the water slower. This was because in hot was particles get separated faster and move quicker. In cold water particles get closer together and the particles move slower. On Friday we had a sub and each class got a question from the worksheet. My group got question number six, we said that the particles would move faster and further apart, but the seat would never lose its shape. It would never lose its shape because solids are lattice. Each group agreed with was we had said. Also, each group presented great answers and explained them every well. Overall, we learned a lot this week!
