Comparing specific heats of metals, a guided-inquiry investigation. Two metal samples (Al and Pb) have the same mass and the same intitial temperature are each placed in separate 50.0 grams of cool water at the same temperature. Which metal will raise the temperature of the 50 grams of water the most? The metal with the higher specific heat will release more heat as it cools and thus will raise the temperature of water more compared to a metal with a lower specific heat. This interactive demonstration focuses on helping students gain a better conceptual understanding of heat, temperature, and specific heat.
