You make a drink by adding 50 g of ice at -7 celcius, 300mL of Cola at 4 celcius and 25mL of rum at 20 celcius into a 250g glass also at 20 celcius. Cp Cola 4.19 J/gK, Cp Rum 3.25 J/gk and Cp Glass 0.84 J/gk.
A) What is the final state of the drink assuming instant heat transfer between the components (show how you arrived to this conclusion)
B) You promptly forget about the drink. By the time you get back to it, its temperature is 15 celcius. Determine the amount of heat absorbed( Assume liquids retain their respective heat capacities)
