The Law of DuLong and Petit
The Law of DuLong and Petit states that the heat capacity per mole of many metals is approximately 6.0 calories per mole-degree C. Knowing that the specific heat capacity of three metals in Joules per gram-degree C. is 0.45 for Fe, 0.24 for Ag, and 0.13 for Au. Do these metals agree with the Law of DuLong and Petit? How do you know this? Using your understanding of bonding in metals, explain why this law appears to hold.
