An adventurer brings an insulated, airtight cylinder containing 0.15 mol of argon gas (Ar) to assist in inflating a portable shelter. The initial temperature and pressure of the gas are 120°C and 2.5 atm, respectively. As the climber inflates the shelter, the gas expands adiabatically until the pressure drops by forty percent. Determine the argon gas's final temperature.
