Revie The main reason that distillation is a costly method for purifying water is the high energy required to heat and vaporize water. Part A Using the density, specific heat, and heat of vaporization of water from Appendix B in the textbook, calculate the amount of energy required to vaporize 1.00 gal of water beginning with water at 25 °C. Express your answer using two significant figures. E = 9700 kJ Submit Previous Answers Correct The volume of the water, given in gallons, must first be converted to grams using the density from the appendix. 3780 gal x 4g xIL x 1000 mL 1 gal * 1.057 qt 0.99707 g H2O 1 ml 1.43 x 107 g H20 1L First, the water needs to be heated from 25 °C to 100 °C. The heat associated with this process is calculated using the specific heat of water from the appendix. 9 = mcAT %3D 1.43 x 107 g H,0 x 4.184 J x (100°C – 25°C) x 1 kJ g.°C x (100°C — 25°С) х 1000 J 4.481 x 10° kJ Once the water reaches 100 °C, it must then be vaporized.
