JEE Main & Advanced Physics Thermodynamical Processes Question Bank Adiabatic Process

  • question_answer
    One gm mol of a diatomic gas \[(\gamma =1.4)\] is compressed adiabatically so that its temperature rises from \[{{27}^{o}}C\] to \[{{127}^{o}}C\]. The work done will be

    A)            2077.5 joules                        

    B)            207.5 joules

    C)            207.5 ergs                              

    D)            None of the above

    Correct Answer: A

    Solution :

                       \[W=\frac{R}{\gamma -1}({{T}_{1}}-{{T}_{2}})\]               \[=\frac{8.31\times \{(273+27)-(273+127)\}}{1.4-1}=-2077.5\ joules\]
