Outline:Balloons and Buoyancy Open the simulation in Java file format. About the PhET simulation interface. Change in temperature and pressure as the gas molecules move. Effect of pressure, temperature and volume on the motion of the balloon. Effect of increase in gravity on the motion of the balloon. Demonstrate buoyancy using a Hot Air Balloon, Rigid Hollow Sphere and Helium Balloon. Add gas molecules to the chamber manually and using the pump. Show that only a few particles of gas possess higher kinetic energy and speed. Relation between change in pressure with change in number of particles. Relation between change in pressure and temperature.
