The fact that most solids have molar heat capacities of approximately 3R,where R is the universal gas constant,is known as

Question

Quizplus · Accepted Answer

The Dulong-Petit law states that most solids have molar heat capacities of approximately 3R. This law was discovered empirically in the early 19th century and is named after its discoverers, Pierre Louis Dulong and Alexis Thérèse Petit. The equipartition theorem and Joule's principle are related to different aspects of thermodynamics, but they do not specifically explain the molar heat capacities of solids. The first law of thermodynamics is a fundamental principle that relates to the conservation of energy, but it is not directly related to the molar heat capacities of solids.
