Heat capacity of ideal gases

For ideal gases, the relationship between \({C}\)\({p}\) and \({C}\)\({v}\) is

      \({C}\)\({p}\) - \({C}\)\({v}\) = \({R}\)

The ideal gases have specific heat capacities

      monoatomic ideal gas ∶  \({C}\)\({v}\) = \(\frac{3}{2}\) \({R}\),  \({C}\)\({p}\) = \(\frac{5}{2}\) \({R}\)

      diatomic ideal gas∶  \({C}\)\({v}\) = \(\frac{5}{2}\) \({R}\),  \({C}\)\({p}\) = \(\frac{7}{2}\) \({R}\)
