PSQ 1. You froze some chicken broth into ice cube (each has a mass of 8 g and temperature of -18C) in your freezer. Today you take 5 ice cubes out of the freezer, immediately pour boiling water onto it inside an insulated food bowl and have an instant warm soup with a temperature of 60C. Assume the broth has the same thermal properties as water (Crce = 2.1 9:070, _ J J Cwater 4-18 9'00, Lf = 334?) a) How much heat is needed to warm the ice cubes up to its melting temperature? b) How much heat is needed to melt the ice cubes? c) How much heat is needed to make the broth reach the nal temperature? d) How much heat is totally gained by the ice cubs during the process? PSQ 2. To make the soup in PSQ 1 inside the insulated food bowl, a) how much heat needs to be removed (lost) from the boiling water? Use your answer from PSQ 1. (Option: If you do not have an answer for PSQ 1, you can use this alternative data: 20000 J heat is totally gained by the ice cubes during the process) b) What is the nal temperature for the added hot water? c) How many mL of the boiling water (100C) needs to be added into above bowl (density of water is 1%)
