The molar heat capacity at 25°C should be close to 25 J/K-mol for all of the given elements except
Options:
Answer:
B
Solution:
Solid metals obey Dulong and Petit, C ≈ 3R = 24.9 J/K-mol (Cu 24.4, Ag 25.4, Zn 25.4). He is a monatomic gas with Cp = 5/2R = 20.8 J/K-mol (Cv = 12.5), so it is the exception. Matches (b).
