This lab was extremely interesting. We were given a jar, a bag, and a rubber band. First we put the bag over the open part of the jar. Then, we tied a rubber band around the part of the bag that covered the opening of the jar. After that process was done, we pushed the bag inside the jar and felt a bit of resistance. However, when we pulled the bag out of the jar, there was so much resistance, and we were unable to pull out the whole bag. As parts of the bag were pulled out, other parts went in. The reason for this was because the air got trapped inside, making the air pressure high and unable to completely pull out.
Coming from this lab, a hypothesis I can make would be that a balloon would be affected by air pressure, as it travels up through the atmosphere. The big three reasons behind this are temperature, water vapor, and altitude, which all affect air pressure. As the temperature gets higher, air pressure gets lower. As the water vapor increases the air gets denser, or higher in air pressure. As the altitude increases, the air pressure gets decreases. The balloon would do many things as it traveled up through the atmosphere. The air pressure would decrease due to the altitude increasing. Depending on the weather as well, the temperature and water vapor would also lay drastic impacts on the air pressure. The balloon would travel up for a little while and then pop. This would be due to the change in air pressure.
Air pressure causes many things to occur. The air pressure is affected by elevation, temperature, and water vapor, as shown in the lab.
