Two solid objects, A and B, are both at room temperature and then placed in boiling water. The objects are left in the boiling water for 10 minutes, ensuring they are heated up to the same temperature as the boiling water. Each is then lifted out and placed in separate beakers containing 1000 g of water at 10.0°C. Object A increases the water temperature by 1.50 °C; object B increases the water temperature by 7.20 °C. In neither case does a chemical reaction occur. Which of the following must be true? O The heat capacity of object B is greater than the heat capacity of object A. O The masses of objects A and B are equal. The heat capacities of objects A and B are equal. O The heat capacity of object B is less than the heat capacity of object A.
