1 litre of water is boiled reversibly inside a pressure cooker The dead weight valve whistle weighing 50 gm lifts up by 2 Cm at 107 C and some steam escapes out The whistle blows 10 times in 5 minutes The Entropy change of the system after 5 minutes is xx 10 3 J K if internal energy change during the process in 10J calculate the value of x Report your answer in single digit obtained by adding up first two digits of your answer 5 Assume steam lost to be of negligible volume and consider each step to be reversible
