When the 3.0 kg cylinder fell 500 m, the final temperature of the water was °c and the change in temperature was °c. when the 9.0 kg cylinder fell 500 m, the final temperature of the water was °c and the change in temperature was °c.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
