On a beautiful summer day a group of friends have a picnic. Of course there is a six pack of beverage on ice for refreshment. Each aluminum can weighs 38.5g and contains 12.0 fluid ounces of beverage. The specific heat of of aluminum is 4.10J/gC. The density of the beverage is 1.07 g/mL. a)How much heat must be absorbed by the six pack to lower its temperature from 25.0C to 5.0C?b)How many grams of ice must be melted to cool the beverage?
