For and ideal gas straight R over straight C subscript straight v equals 2 over 3 comma space what is the atomicity of gas?

Solution

  W e space h a v e comma space

space space space space space straight R over straight C subscript straight v equals 2 over 3 space

rightwards double arrow space space straight C subscript straight v equals 1.5 space straight R space

A l s o comma space space space space straight C subscript straight P minus straight C subscript straight v equals straight R

T h u s comma space space space straight C subscript straight P equals 2.5 straight R space

N o w comma space space straight y equals straight C subscript straight P over straight C subscript straight v equals fraction numerator 2.5 over denominator 1.5 end fraction equals 5 over 3
Thus the gas is monoatomic.
