ANSWER:Problem 13SAQA mixture containing 21.4 g of ice (at exactly 0.00 0C) and 75.3 g of water (at 55.3 OC) isplaced in an insulated container. Assuming no loss of heat to the surroundings, what is thefinal temperature of the mixturea) 22.5 OCb) 25.4 OCc) 32.6 OCd) 41.9 OC Step by step solutionStep 1 of 2Specific heat formula is as follows. ……………………………..(1)From the given,Initial temperature of ice =Mass of ice = 21.4 gInitial temperature of water =Mass of ice = 75.3 g’Let’s assume the final temperature of the mixture = xAt the fusion of ice = 6.02 kJ/molLet’s calculate the fusion energy of ice at\nHence, fusion energy of an ice is 7153.14 J.
