    If \[{{C}_{p}}\]and \[{{C}_{v}}\] denote the specific heats (per unit mass) of an ideal gas of molecular weight M where R is the molar gas constant.

    A) \[{{C}_{p}}-{{C}_{v}}=\frac{R}{{{M}^{2}}}\]         

    B) \[{{C}_{p}}-{{C}_{v}}=R\]

    C) \[{{C}_{p}}-{{C}_{v}}=\frac{R}{M}\]        

    D) \[{{C}_{p}}-{{C}_{v}}=MR\]

    Correct Answer: C

    Solution :

    \[{{C}_{p}}-{{C}_{v}}=R\] \[\therefore \]  \[M{{c}_{p}}-M{{C}_{v}}=R\]                 \[{{C}_{p}}-{{C}_{v}}=\frac{R}{M}\]
