Gas Attribute: The specific heat capacity is the thermodynamic attribute of a material that determines the energy required by that material in order to undergo a unit change in its temperature. Therefore, the specific heat capacity is the function of mass of the material considered, the energy re...
Two bodies of specific heats C1andC2 having same heat capacities are combined to form a single composite body. What is the specific heat of the composite body? View Solution The molar specific heat capacity of all monatomic gases is the same. Is this ture of false ? (Assumed ideal nature....
= 7/2nR for a diatomic “ideal” gas. Question What is the internal energy of a monatomic gas? A. U = 3 2 R B. U = 3 2 RT 3 C. U = 3 2 nR D. U = 3 2 nRT Question If the heat capacity of a diatomic gas is 5/2nR, what is the ...
FREQUENCY SPECTRA OF FREE LATTICES AND PARTICLE SIZE EFFECTS ON THE HEAT CAPACITY OF SOLIDS The effect of particle size on the heat capacity of solids has been investigated using lattices with free boundaries as models. A monatomic lattice shows a... Patterson,D. - 《Canadian Journal of Chemist...
where R is the general gas constant. For diatomic molecule Similarly, by taking the value of Q from Eq. (2.2), and the value of ΔU for diatomic molecules from the equipartition principle of energy, we can find the heat capacity of a diatomic molecule at constant volume, as given in Eq...
translational degrees of freedom. For diatomic, triatomic, and larger molecules the rotational modes may become active at sufficient temperature. For multiatomic molecules the internal vibrational degrees of freedom also may become active. In the case of a monatomic gas such as helium under const...
The Cp/Cv ratio for Heagrees well with the theoretical value obtained from the classical equipartition theoremfor a monatomic gas with three translational degrees of freedom. The experimental Cp/Cv ratio for N2 is closer to the theoretical value without vibrational contribution [7/5], than the ...

For example, the specific heat of helium (a monatomic gas) is 12.47 kJ/(kmol K) or 3.1156 kJ/(kg K) while the molar specific heat of hydrogen (a diatomic gas) is 20.53 kJ/(kmol K) or 10.183 kJ/(kg K) (Cengel and Boles, 1998). However, it should be noted that this is not ...
