An iron ball and an aluminum ball of mass 100 g each are heated to the same temperature and then cooled to a temperature of 20°C. The heat lost by the iron ball is 3.6 kJ. The heat lost by the aluminum ball is 7.2 kJ. What does this imply?
As the temperature changes and their masses are the same, heat lost by the balls is directly proportional to their specific heat values. The heat lost by the aluminum ball is higher implies aluminum has higher specific heat.
