SUMMARY
The discussion centers on the challenges of obtaining thermodynamic values for solid CO2, specifically internal energy and entropy, using tools like REFPROP (by NIST) and EES. Both tools lack data below 212K, despite CO2 sublimating at approximately 195K at one atmosphere. Participants emphasize the importance of understanding specific heat capacity and latent heat for solid CO2, highlighting a gap in available thermodynamic data for this state.
PREREQUISITES
- Understanding of thermodynamic principles, particularly phase changes.
