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 k ...continues
