An ideal gas having pressure 'P' , volume 'V' and temperature 'T' is allowed to expand adiabatically until its volume becomes 42V while its temperature falls to T/2, the degrees of freedom of gas molecules are

T1⋅V1γ−1=T2⋅V2γ−1TVγ-1=T242Vγ-1 solving γ=75γ=1+2f f=5find γ and put in equation γ=1+2f and find f

Detailed Solution

$T_{1} \cdot V_{1}^{γ - 1} = T_{2} \cdot V_{2}^{γ - 1}$

${TV}^{γ - 1} = \frac{T}{2} {(4 \sqrt{2} V)}^{γ - 1} solving γ = \frac{7}{5}$

$γ = 1 + \frac{2}{f} f = 5$

find $γ and put in equation γ = 1 + \frac{2}{f}$ and find f
