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. Determine the work done on the gas during this process, the energy transferred to the gas through heating, and the change in the internal energy of the gas. Show all work and explain your thought process in words. Explain how you know whether your answer is reasonable or not.
