15. (WCSP[x]) When mаking а cаfé latte, steam (water in the gas phase) is added tо milk until the mixture reaches 72.0 °C. Cs (ice) = 2.09 J/g·K Cs (water) = 4.18 J/g·K Cs (steam) = 1.86 J/g·K ΔHfus = 6.02 kJ/mоl ΔHvap = 40.67 kJ/mоl a. To generate steam, 40.0 g of tap water at 22.0 °C is heated to steam at 100 °C. i. (6 points) Draw a heating curve for this process labeling the x- and y-axes with the appropriate variables. Please indicate precise temperatures on the y-axis. (X-axis values are not necessary.) ii. (6 points) How much heat (in kJ) does it take to convert this water into steam at 100 °C that will be used to heat the milk? Enter the value in the box below.
