When you open a can of soda (or beer), compressed CO2 expands irreversibly against the atmosphere as it bubbles up through the drink. Assume that the process is adiabatic and that the CO2 has an initial pressure of 3 bar. Take CO2 to be an ideal gas, with a constant heat capacity of Cp=37J/1molK. What is the final temperature of the CO2 after it has reached atmospheric pressure?
