Consider a glass of ice water at 0 °C. Moisture from the air is observed to condense on the outer sides of the glass. This condensation causes the ice in the glass to melt faster than if there were no condensation. For this problem use LvLv= 2430 kJ/kg for the latent heat of vaporization of water at 37 °C as a better approximation than LvLv for water at 100 °C.) Determine the mass of ice, in grams, in the glass that would melt as a result of the condensation of 6.6 g of water from the air onto the sides of the glass.
