Physics bouyancy
1. Why does a hot air balloon float even though it is so heavy? The buoyancy force of the hot air balloon is more than the weight and the hot air balloon has a lower density than the air outside and that is why buoyancy occurs and a hot air balloon floats.
2. What makes balloons float when they are full of air but not float when they are deflated? The hot air weighs less than the air inside the balloon causing the balloon to float when full of hot air.
3. Starting with a hot air balloon, figure out how to make the balloon float. What factors affect the balloon floating or sinking? Explain three of these factors and your understanding of why this works as it does. Hot air is less dense than warm air, so when the air is heated in the balloon the balloon will start to rise. The balloon begins to fall when there is no more hot air in the balloon.
4. Move to the rigid hollow sphere. What does it mean that the sphere is “rigid?” A rigid sphere is one that possesses an impenetrable shell.
5. Play with the parameters of the simulation and get the sphere to float. How is the sphere floating similar to and different from the floating hot air balloon?
The sphere and the hot air balloon are similar in the fact that they both have a bobbing motion when nothing is added to their system. The sphere sinks when species are added inside of the sphere, but when we add gas inside the hot air balloon the hot air balloon began to float.
