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 process, rms speed of gas molecules has become a^(1//2)times of its initial value. What will be the value of C_vso that energy transferred by the heat to the gas is .a. times of the initial energy. (Delta Q = aPV)

Answer»

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