A 124-mL bubble of hot gas initially at 212 °C and 1.80atm is emitted from an active volcano. What is the final temperature, in degrees Celcius, of the gas in the bubble outside the volcano when the final volume of the bubble is 138 mL and the pressure is 0.800 atm, if the amount of gas does not change?
