WebSo the conversion factor is 16 g/mol = 1 DP unit. (By the way, Petit & Dulong did not call their heat units calories. They employed specific heat units in which water has a value of 1; I recognized those units to be equal to cal/g.) Exercise 2 is an exercise in data analysis. The object here is to find the relationship between the two variables. WebQuestion: Relationship between Specific Heat and Atomic Mass Based on specific heat measurements, Pierre Dulong and Alexis Petit proposed in 1818 that the specific heat of an element is related to its atomic weight (atomic mass). Thus, by measuring the specific heat of a new element, its atomic weight could be readily established.

WebMay 23, 2024 · Dulong-Petit’s Law: The product of specific heat and the atomic mass of an element in the solid-state is approximately equal to 6.4. OR Atomic heat of a solid element is nearly equal to 6.4. Limitations of Dulong-Petit’s Law: This law is applicable to elements which are in solid state. This law Is applicable to the heavier element. WebConfirm that θE has the dimensions of temperature, and express the criterion for the validity of the high-temperature form of the Einstein equation in terms of it.
