Expert Solution

Solution:- The given process is a constant volume process and it has been assumed that no heat transfer takes place across the walls of the rigid tank. Standard values of C​​​​​​V (Specific heat at constant volume) and R (Universal gas constant) for air have been assumed to solve the problem.
