Question

One mole of an ideal monoatomic gas undergoes two reversible processes ($A → B$ and $B → C$) as shown in the given figure:

$A → B$ is an adiabatic process. If the total heat absorbed in the entire process ($A → B$ and $B → C$) is $R𝑇_2\ ln\ 10$, the value of $2 log\ 𝑉_3$ is ___ . [Use, molar heat capacity of the gas at constant pressure, $𝐶_{p,m} = \frac 52R$]

Answer 1

the correct answer is 7
