A <b>diatomic gas molecule</b> has 6 <b>degrees of freedom</b>. ... also count <b>degrees of</b>

the adiabatic ... while for a <b>diatomic gas</b>, with 5 <b>degrees of freedom</b> (at room 
temperature: 3 translational and 2 rotational <b>degrees</b> ... states become accessible 
to <b>molecular</b> gases, thus increasing the <b>number of degrees of freedom</b> and 
lowering γ. In classical statistical mechanics, the equipartition theorem relates the 
temperature of a system ... Such a <b>degree of freedom</b> is said to be &quot;frozen out&quot; 
when the thermal energy is much smaller than ... denote the average of the 
enclosed <b>quantity</b>, ... Therefore, the heat capacity of a <b>gas</b> of N <b>diatomic</b> 
<b>molecules</b> is predicted to be&nbsp;... The molar heat capacity of a chemical substance is the amount of energy that 
must be added, ... Namely, when heat energy is injected into a <b>gas</b> with 
<b>polyatomic molecules</b>, only part of it will go ... If the <b>number of degrees of freedom</b> 
of the is f, then each <b>molecule</b> would be holding, on average, a total energy equal 
to fkT/2. The kinetic theory of <b>gases</b> is a historically significant, but simple model of the 
thermodynamic behavior of <b>gases</b> with which <b>many</b> principal concepts of 
thermodynamics were established. The model describes a <b>gas</b> as a large

<b>molecular</b> mass, but also on the <b>number of degrees of freedom</b> that the 
<b>molecules</b> have. A <b>molecular</b> vibration is a periodic motion of the atoms of a <b>molecule</b> relative to 
each other, ... A <b>diatomic molecule</b> has one normal mode of vibration, since it can 
only stretch or ... The <b>number</b> of vibrational modes is therefore 3N minus the 
<b>number</b> of translational and rotational <b>degrees of freedom</b>, or 3N–5 for linear and 
3N–6&nbsp;...
