With the given data, answer the following questions:1. Did the metal or the water have the greater change in temperature? (Answer this for trial 1, 2, & 3)2. In step 3 of the calculations, we used the same number for "heat lost by the metal" and "heat gained by the water." Explain why these two numbers are the same.3. Explain why the temperature change of the metal is much larger than the temperature change of the water if the quantity of heat lost by the metal is the same as the quantity of heat gained by the water. Use one of the trials as a specific example. Use your data to help justify your conclusion. ?4. Compare the specific heat of water to the specific heat of the metal. Which is bigger? (Answer this question for all 3 separate trials) 5. What does a higher specific heat indicate about a substance in terms of energy gained and temperature change?
