A cylinder filled with 50 gm of air at 1 atmosphere pressure and a temperature of 20 c is adiabatically but irreversibly compressed to 10 atmosphere s pressure .when equilibrium has been established ,the final temperature is found to be 320 c ,Determine how much work was done on the system and the change in entropy during the compression .if a reversible process had occurred between the same two state points, would heat has been added or removed? compute the value of the exponent in the relationship pv =pv= constant describing the irreversible compression process ? plot the reversible and irreversible process on p-v and t-s diagrams.
