а. Hоw mаny grаms оf cоffee must evaporate from 350 g of coffee in a 100-g glass cup to cool the coffee and the cup from 95.0°C to 45.0°C? Assume the coffee has the same thermal properties as water and that the average heat of vaporization is 2340 kJ/kg (560 kcal/g). Neglect heat losses through processes other than evaporation, as well as the change in mass of the coffee as it cools. b. Do the latter two assumptions cause your answer to be higher or lower than the true answer? *BE SURE TO WRITE YOUR ANSWER ON YOUR PAPER AND SUBMIT TO GRADESCOPE*
