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 Ī³(=CPCv) are given, respectively , by :
A U=5/2 RTandĪ³=6/5
B U=5 RTandĪ³=7/5
C U=5/2 RTandĪ³=7/5
D U=5 RTandĪ³=6/5
