  • question_answer
    During an adiabatic process, the pressure of a gas is found to be proportional to the cube of its absolute temperature. The ratio, \[{{C}_{p}}/{{C}_{V}}\] for the gas is                                                                             [AIEEE 2003]

    A)  4/3

    B)                   2    

    C)  5/3      

    D)       3/2

    Correct Answer: D

    Solution :

    [d] Given,         
                In an adiabatic process
                 constant
               
                                 ... (ii)
                Comparing Eqs. (i) and (ii), we get
