An ideal gas undergoes a process in which PV^(-a)= constant, where V is the volume occupied by the gas initially at pressure P. At the end of the porcess, .rms. speed of gasmolecules has become a 1/2 times of its initial value. What will be the value of C_v so that energy transferred in the form of heat to the gas is.a. times of the initial energy

Answer»

`((a^(2)+1)R)/(a^(2)-1)`
`((a^(2)+1)R)/((a^(2)+1))`
`((a^(2)+1)R)/((a-1))`
`((a-1)R)/((a+1))`
