The container is warmed to 0 degrees C a temperature at which CO2 is a gas. a. What is the gas pressure in ATM. b. The gas then undergoes an isothermal compression until the pressure is 2.40 ATM, immediatly followed by an isobaric process which changes the volume to 2000 cm^3. What is the final temperature of the gas?
