Using the density, specific heat, and heat if vaporization of water from Appendix B, calculate the amount of energy required to vaporize 1.00 gal of water beginning with water at 15∘C. Express your answer to two significant figures.
Density: 0.99987 g/mL at 0∘C. 1.00000 g/mL at 4∘C. 0.99707 at 25∘C. 0.95838 at 100∘C.
Heat (enthalpy) of vaporization: 44.94 kJ/mol at 0∘C. 44.02 kJ/mol at 25∘C. 40.67 kJ/mol at 100∘C.
Specific heat: 2.092 J/g-K= 2.092 J/gx∘C for ice at -3∘C. 4.184 J/g-K= 4.184 J/gx∘C for water at 25∘C. 1.841 J/g-K= 1.841 J/gx∘C for steam at 100∘C.
