Estimate how much heat is absorbed when 1.00 g of Instant Car Kooler vaporizes. Comment on the effectiveness of this spray in cooling the interior of a car. Assume the spray is 10% C₂H₅OH(aq) by mass, the temperature is 55 °C, the heat capacity of air is 29 J mol^-1 K^-1, and use Δ_vapH data from Table 12.4.
