PROBLEM 8.10 Assuming that Coca Cola has the same specific heat as water [4.18 J/ (g °C)], calculate the amount of heat (in kilojoules) transferred when one can (about 350 g) is cooled from 25°C to 3°C. 

The enzymic synthesis of sucrose resulted in some publicity that came to the attention of officials of the Coca Cola Company, who were having difficulty in obtaining sucrose because of wartime rationing. The company sent a representative to Berkeley to ascertain whether commercial quantities of sucrose could be made by the enzymic method.
