有沒有液體的碘和二氧化碳?

Yes, both iodine and CO2 has liquid form. You have to change pressure and temperature. You can refer to the reference website and see the phase diagram of iodine and CO2.

For example, iodine is in liquid form if the pressure is 1 atm and the temperature is between 113.6-184.4 C. CO2 is in liquid form if the pressure is > 5.1 atm but < 72.9 atm and the temperature is between -56.7 - 31 C. Please refer to the figures 13.18 and 13.19.
