Molecules of an ideal gas are known to have three translational degrees of freedom and two rotational degrees of freedom. The gas is maintained at a temperature of T. The total internal energy, U of a mole of this gas, and the value of γ (=C?/C?) are given, respectively, by:

Option 1 - <p>U = (5/2)RT and γ = 6/5</p>
Option 2 - <p>U = 5RT and γ = 7/5<br>&lt;!-- [if !supportLineBreakNewLine]--&gt;<br>&lt;!--[endif]--&gt;</p>
Option 3 - <p>U = (7/2)RT and γ = 7/5<br>&lt;!-- [if !supportLineBreakNewLine]--&gt;<br>&lt;!--[endif]--&gt;</p>
Option 4 - <p>U = (5/2)RT and γ = 7/5</p>
