A student wants to measure the temperature change of water after adding a 10 cm3 block of iron to container 1 and a 10 cm3 block of lead to container 2. Both blocks were heated to 40°C before being added to the water. The image below shows the experiment immediately after adding the blocks. Why did the temperature increase more for container 1 even though each 10 cm3 block was heated to 40°C and placed in 100 mL of water at 25°C? A. Different materials can have different rates of sinking. B. Different materials can have different densities. C. Different materials can have different rates of dissolving. D. Different materials can have different capabilities of transferring heat.
