1. What did I learn this week? Today in lab, we learned about and developed a particle model of the plunger. When the plunger is pushed down on a smooth surface, it sticks. When the plunger gets pushed down, the air is forced out and cannot come back in because a vacuum is created inside. There is no space for the air to go inside, making it stick to the surface. We also learned about why ice melts faster on metal than on wood. We concluded that metal has less gaps/holes in their particle makeup. When the ice hits the ice, there are more collisions happening which heats up the ice and causes it to melt. The wood's particle makeup has more air pockets causing less collisions. 2. Which parts did I find confusing? The most confusing part of the lab was explaining why ice melts faster on metal. This process took forever for me to figure out. Once we understood the particle makeup of the materials, it helped me to understand particle collision better. 3. How can I apply this to teachin...
Hi Sid!
ReplyDeleteGreat post! I know that with each energy conversion, some heat is lost, leading to increased thermal energy! But, I don't know the exact answer to your questions, it is a great one! Thank you for sharing your thoughts and questions!
