A balloon filled with ideal Helium gas (a monatomic gas) is tethered outside, and over time the balloon contracts from a volume of 1.15×10^3 m^3 to a volume of 1.05×10^3 m^3 . Assume that as it is contracting, the balloon maintains a constant pressure of 1.00 atm ( 1.013×10^5 Pa). The balloon contains 50,000 moles of Helium gas. a) Complete the following: i. Sketch a PV diagram for this process below. Label the pressures and volumes relevant at the initial and final times. ii. Find the work done by the environment on the gas during this process. Show your work! iii. Answer the following question: Did energy in the form of work enter or leave the system of Helium gas during the contraction? b) Find the change in the internal energy of the Helium gas during the process. c) Find the amount of heat transfer to or from the environment during this process and then answer the following question: Was the environment (outside atmosphere) at a higher or lower temperature than the helium gas during the contraction? Show your work and explain your answer!
