A) 0.5R
B) 1.5R
C) 2R
D) 2.5R
Correct Answer: A
Solution :
Given \[{{\left( \frac{{{T}^{7}}}{{{P}^{2}}} \right)}^{1/5}}=\]constant or \[{{T}^{7/5}}{{P}^{-2/5}}=\]constant ?(1) The standard form of adiabatic equation \[{{T}^{\gamma }}{{P}^{1-\gamma }}=\text{constant}\] ?(2) Now comparing equation (1) with standard form equation (2), we get \[\gamma =\frac{7}{5}\] the gas is diatomic so, \[{{C}_{v}}=\frac{5}{2}R\]You need to login to perform this action.
