The Dulong–Petit law, a thermodynamic law proposed by French physicists Pierre Louis Dulong and Alexis Thérèse Petit, states that the classical expression for the molar specific heat capacity of certain chemical elements is constant for temperatures far from the absolute zero. In modern terms, Dulong and Petit found that the heat capacity of a mole of ma… WebSOLVED: 'The specific heat of a metal was found to be 0.38 Jlg:"C. When 0.5007 gof this metal was heated in a stream of chlorine gas, it produced 1.0586 g of a metal chloride; MCL , Use the law of Dulong and Petit to estimate the molar mass of the metal first: Determine the formula of the metal chloride and the accurate atomic weight ofthe metal.
Webstatistical physics [1]. What Dulong and Petit had found was, in their own words, that “the atoms of all simple bodies have exactly the same capacity for heat”1 or, more specifically, that the product of the specific heat of 13 chemical elements times their atomic mass (hence the molar specific heat) was approximately constant. WebHeat Capacity of an Ideal Monatomic Gas at Constant Volume. We define the molar heat capacity at constant volume CV C V as. CV = 1 n Q ΔT,with V held constant. C V = 1 n Q Δ T, with V held constant. This is often expressed in the form. Q =nCV ΔT. (2.13) (2.13) Q = n C V Δ T. If the volume does not change, there is no overall displacement ...
