A balloon is filled with 0.0020 m^3 of air at room temperature and at 1.01 x 10^5 Pa of atmospheric pressure. It is then placed inside a vacuum chamber where the air pressure is reduced to 500 Pa. This is an isothermal process, where the temperature is kept constant, and the balloon can reach whatever volume is allowed. Draw a sketch showing the initial and final state of the balloon. Make sure all quantities are clearly labeled. Draw a quantitative PV-graph showing how the pressure and volume of the gas inside the balloon change during this process and a qualitative energy bar chart showing the changes of the energy within the system. Please be as detailed as possible.

A balloon is filled with 0.0020 m^3 of air at room temperature and at 1.01 x 10^5 Pa of atmospheric pressure. It is then placed inside a vacuum chamber where the air pressure is reduced to 500 Pa. This is an isothermal process, where the temperature is kept constant, and the balloon can reach whatever volume is allowed.

  1. Draw a sketch showing the initial and final state of the balloon. Make sure all quantities are clearly labeled.
  2. Draw a quantitative PV-graph showing how the pressure and volume of the gas inside the balloon change during this process and a qualitative energy bar chart showing the changes of the energy within the system.

Please be as detailed as possible.
