Dry ice is solid carbon dioxide (CO2). Figure 7-1 on the following page is a P-H Diagram for CO2. 100 Ibm of dry ice at -100C is heated until it goes directly to gaseous CO2 (no liquid phase) at 80F at 1 atm. a. Estimate the total change in enthalpy of the CO2 using Kopp's Law (Table B.10), the heat of melting (Table B.1), and the heat capacity formula found in Table B.2 of the text. b. Check heat of melting with the enthalpy calculated from Figure 7-1
