Question

22. If the pressure is very low, ice can sublimate at -70 oC, instead of melting and then evaporating To calculate the enthalpy of sublimation (AHsubl) at such temperature, we can take advantage of the properties of state functions. a. In the T vs. Hdiagram below, draw a plausible path to go from H20 (s) at -700C to H20 (g) at the same temperature. oC) 70 H20 (s) H20 (g) b. Write the algebraic expression to calculate 4H 70 for the path you drew in the diagram subl
