Why is CO2 gas "freezing" (it is actually depositing; deposition is the process opposite to sublimation) into
dry ice? Prove it mathematically using equations and logic. Be concise!
Hint: What type of a process is this, isothermal, adiabatic, isochoric, isobaric? Are q, w, \(\Delta U\), \(\Delta H\) negative,
positive or zero?
Hint: The question uses logic very similar to the "tables" that we practiced in class (Chapter 2).
