The molar specific heat of a gas is defined as `C=(Dq)/(ndT)` Where `dQ`=heat absorbed `n` = mole number `dT` = change in temperature The equation of
Correct Answer - B `C=(R)/(gamma-1)+p(dV)/(dT)` `=(R)/(gamma-1)+alphaV.(R)/(2alphaV)=(R)/(gamma-1)+(R)/(2)=(R(gamma+1))/(2(gamma-1))` `Q=-DeltaU=DeltaU+W , or W=-2DeltaU` `C=(R)/(gamma-1)+((-2RdT)/((gamma-1)dT))=(R)/(1-gamma)` `pdV=(-2RdT)/(gamma-1)` `(RT)/(V)dV=(-2)/(gamma-1)RdT(dT)/(T)=-((gamma-1))/(2)(dV)/(V)` log `T=-((gamma-1))/(2)logV =logV^(-(gamma-1)/(2))+logK` or log `TV^((gamma-1)/(2))=` constant
