The molar heat capacity (C_p) of water at constant pressure is 75 J.K-1.mol-1. The increase in temperature (in K) of 100 g of water when 1 k.J. of heat is supplied to it is. ( ) A. 2.4 B. 0.24 C. 1.3 D. 0.13 相关知识点: 试题来源: 解析 A 反馈 收藏 ...
The molar heat capacity of non-superconductive PdH x ( x ≦ 0.78) is measured in the temperature range from 2 to 7 K. The γ-coefficients and Debye temperatures are determined of samples with different atomic ratio x = H/Pd and produced with different methods. The γ-coefficients of PdH ...
On the basis of the Debye Law [11], the molar heat capacity of Li[B.sub.5][O.sub.8] x 5[H.sub.2]O determined in this work has been fitted and shown in (1). Heat Capacity and Thermodynamic Property of Lithium Pentaborate Pentahydrate where [a.sub.i] and [C.sub.p] are the ...
Like other molecules, water has a distinct specific heat capacity that describes the heat needed to raise the temperature by 1 unit for one gram of water. From the specific heat capacity of water, we can determine the molar heat capacity using the molar mass of wa...

【题目】比热容问题The molar heats of fusion and vaporization for water are 6.02kJ/mol and 40.6kJ/mol, respectively, and the specific heat capacity of liquid water is 4.18J/gC. Given that the specific heat capacities of ice and steam are 2.06J/g℃ and 2.03J/g℃. Calculate the total ...
The molar heat capacity (20) is defined and measured at constant pressure, because the inter-atomic distance and the sound velocity change with changing pressure, but the theory’s input parameters that enter the variable \(\alpha \) are assumed to be constant. The assumption that v and a ...
From F, we obtain the molar heat capacity in equation (2). 9. Cabrera, I. et al. Excitations in the quantum paramagnetic phase of the quasi-one-dimensional Ising magnet CoNb2O6 in a transverse field: Geometric frustration and quantum renormalization effects. Phys. Rev. B 90, 014418 (...
