3. A sample of a metal with a mass of 30 g was heated to 175°C. It was then quickly moved to an insulated container holding 30 g of water at 0°C. The final temperature of both the metal and the water was 50°C. Which of the following can be concluded? A. The metal temperature changed more than the water temperature did; therefore, the heat capacity of the metal must be less than the heat capacity of the water. B. The final temperature is less than the average starting temperature of the metal and the water; therefore, the total energy of the metal and water decreased. c. The metal temperature changed more than the water temperature did, therefore, the metal lost more thermal energy than the water gained. D. The metal temperature changed more than the water temperature did therefore, the water lost more thermal energy than the metal gained.
