7. Calculate the enthalpy change, ΔH, for the process in which 36.2 g of water is converted from liquid at 3.2 ∘C to vapor at 25.0 ∘C .

For water, ΔHvap = 44.0 kJ/mol at 25.0 ∘C and Cs = 4.18  J/(g⋅∘C) for H2O(l).

9. The instruction booklet for your pressure cooker indicates that its highest setting is 13.4 psi . You know that standard atmospheric pressure is 14.7 psi, so the booklet must mean 13.4 psi above atmospheric pressure. At what temperature in degrees Celsius will your food cook in this pressure cooker set on "high"?
